0:04:58 > 0:05:01Sorry, Benson. We're trying to get things to suck up.
0:05:01 > 0:05:05- Do you think you can help us?- Oh, ya, man, of course I can help you.
0:05:05 > 0:05:06How would you suck up apples?
0:05:06 > 0:05:10It's all to do with pressure and molecules.
0:05:10 > 0:05:14I know all about molecules. Everything's made of molecules,
0:05:14 > 0:05:17- but they're so small that the human eye can't see them.- Di.
0:05:17 > 0:05:23Yeah, man, that's right. But in air, molecules can move around.
0:05:23 > 0:05:26Some areas can have lots of molecules and some areas
0:05:26 > 0:05:29don't have many molecules at all.
0:05:29 > 0:05:32An area with fewer molecules in its surroundings
0:05:32 > 0:05:35is called an area of low pressure.
0:05:37 > 0:05:40This area with fewer molecules
0:05:40 > 0:05:44wants to fill its empty space and will suck more molecules into it.
0:05:44 > 0:05:48This is what we call suction.
0:05:48 > 0:05:51So we need to create an area of low pressure
0:05:51 > 0:05:53so it'll suck more molecules in?
0:05:53 > 0:05:56What? Why on earth are you talking about moles?
0:05:56 > 0:06:00No, not moles. Molecules. Molecules!
0:06:00 > 0:06:04- That's the trouble with goldfish. Terrible memories.- Di.
0:06:04 > 0:06:08Well, at least we know we need to create an area of low pressure.
0:06:08 > 0:06:10OUCHO SPEAKS CACTINIAN
0:06:10 > 0:06:15Maybe we could get a bin and then tip it upside down and then
0:06:15 > 0:06:19hopefully all the molecules will fall out, then we could stick a tube on top,
0:06:19 > 0:06:22then that should suck in molecules from outside the bin.
0:06:22 > 0:06:24- Oh, di.- Oh, this is going to be easy.
0:06:24 > 0:06:26Let's get building!
0:06:33 > 0:06:35- HE SHOUTS:- Wilf!
0:06:36 > 0:06:40So what have you been up to? Actually, let me guess.
0:06:40 > 0:06:43I reckon you've been getting pastry ready for your apple pies.
0:06:43 > 0:06:46No, I like my pastry fresh,
0:06:46 > 0:06:49so I'm going to make it when the apple scrumper is finished.
0:06:49 > 0:06:51Well, you might have to make it today,
0:06:51 > 0:06:56because your apple scrumper is finished. Here it is, look!
0:06:56 > 0:06:58That is an absolute piece of junk.
0:06:58 > 0:07:02You think this is junk because it looks a bit like a bin?
0:07:02 > 0:07:05Yeah, it still has the label on.
0:07:05 > 0:07:09Oh, yeah. All right, I'll level with you. It is a bin.
0:07:09 > 0:07:12But it's a bin full of low pressure.
0:07:12 > 0:07:17When you take that bag off that tube at the end, that will suck up all the apples into the bin.
0:07:17 > 0:07:20Then you can take them out, wash them in here, because you wanted to
0:07:20 > 0:07:22- wash the apples, didn't you?- Di.
0:07:22 > 0:07:25Not with my own hands.
0:07:25 > 0:07:28Yeah, well...you can't have everything, can you?

0:07:39 > 0:07:41Just put them there. Lovely.
0:07:44 > 0:07:46I don't think it's going to work.

0:07:58 > 0:08:02Suck! Suck up! Suck up the apples!

0:08:09 > 0:08:13It WILL work! It's going to work, oh ye of little faith.
0:08:13 > 0:08:15This doesn't look secure either.
0:08:15 > 0:08:17I think we need to start again.
0:08:17 > 0:08:21Yeah, we should probably go back to the van. You go first, we'll follow.
0:08:24 > 0:08:28- You know what?- Hm? - I don't think he likes this.
0:08:28 > 0:08:31It's always the same. We go to their house, they go,
0:08:31 > 0:08:34"Can you build our invention?" We build the invention, they go,
0:08:34 > 0:08:36"Oh, no, don't like it, it's rubbish."
0:08:36 > 0:08:39Then we go and work out what's wrong with it, build another one,
0:08:39 > 0:08:43normally that doesn't work either, and they go, "Oh, fix that."
0:08:43 > 0:08:46And we have to fix that, have to talk to people about science,
0:08:46 > 0:08:49And they always want to make it in three days.
0:08:49 > 0:08:54Why can't we make it in four days or five days or why don't they give us a month, the little slave drivers?!
0:08:54 > 0:08:56What?
0:08:56 > 0:08:59I'm still here, you know.
0:08:59 > 0:09:01Yeah, I knew you were still there.
0:09:01 > 0:09:04Just... Come on, let's go, back to the van.
0:09:08 > 0:09:11Well, Wilf, I've been back to the drawing board
0:09:11 > 0:09:14and I think I've come up with a solution to your little problem.
0:09:14 > 0:09:17What did you say the problem with your invention was?
0:09:17 > 0:09:20- It looks rubbish.- Apart from that? - It doesn't wash the apples itself.
0:09:20 > 0:09:22Besides that?
0:09:22 > 0:09:24It doesn't move.
0:09:24 > 0:09:28Bingo! But it is going to move now because I remembered that Major Cake
0:09:28 > 0:09:32gave us a set caterpillar tracks in exchange for a slice of Battenburg.
0:09:32 > 0:09:35I can paint those up so it doesn't look rubbish any more, whack them on.
0:09:35 > 0:09:39Then we'll put on a washing area as well and, Bob's your uncle -
0:09:39 > 0:09:42if your uncle's name is Bob - you've got your apple scrumper.
0:09:42 > 0:09:45- I am a genius.- But it still doesn't suck up the apples.
0:09:48 > 0:09:50Y... Yes, that is the minor flaw in
0:09:50 > 0:09:54my brilliant plan, but we're full of good ideas, aren't we, Oucho?

0:10:21 > 0:10:23- Di.- Stop reading that magazine.
0:10:23 > 0:10:26Maybe somebody whose name rhymes with "suck".
0:10:26 > 0:10:30It's probably a stupid idea but it might work.

0:11:17 > 0:11:24There's spiders as big as houses, bugs as big as my head and some very friendly mosquitoes.
0:11:24 > 0:11:28Yeah. Scott, we're trying to make an invention called an apple scrumper.
0:11:28 > 0:11:30It needs to suck up apples -
0:11:30 > 0:11:33we tried to make an area of low pressure with an empty bin, but it didn't work.
0:11:33 > 0:11:38Even though you think the container is empty, it's still full of air,
0:11:38 > 0:11:40and air is made of molecules.
0:11:40 > 0:11:42Oh, I see.
0:11:42 > 0:11:46So we need to remove air from the container so it has less molecules?
0:11:46 > 0:11:48That's spot on, dear chap.
0:11:48 > 0:11:53- How can we do that?- I don't suppose you've got a fan handy, have you?
0:11:53 > 0:11:55Oh. Actually, we do.
0:11:55 > 0:11:58- Bit of a weird-looking one. - If you could turn it on, please.
0:11:58 > 0:12:02- Is the fan blowing cool air in your face?- Yeah, it is.
0:12:02 > 0:12:06- It's quite nice, actually. Very cooling.- Ah, a fan...- Hello?
0:12:06 > 0:12:08Scott Stuck? Are you still there?
0:12:08 > 0:12:13Oh. Oh, sorry, dear friend. Just having a bit of a daydream there.
0:12:13 > 0:12:16Can you feel the air molecules being
0:12:16 > 0:12:19pushed out of the front of the fan and into your face?
0:12:19 > 0:12:22Yeah, I can feel it pushing on my face and my hair.
0:12:22 > 0:12:24I hope it's not messing my hair up.
0:12:24 > 0:12:30The area in front of the fan is high pressure and the area behind the fan
0:12:30 > 0:12:32is low pressure and more air molecules
0:12:32 > 0:12:34are being sucked in to fill it.
0:12:34 > 0:12:37Oh, yeah. I can see it sucking up some feathers.
0:12:37 > 0:12:39- I hope that helped.- Yeah, it has.
0:12:39 > 0:12:42We can create an area of low pressure with a fan.
0:12:42 > 0:12:46Putting a fan on the apple scrumper is the key to picking up apples.
0:12:46 > 0:12:47Apple pie in the bag.
0:12:47 > 0:12:51Oh, it's been a long time since I had an apple pie.
0:12:51 > 0:12:54How about you?
0:12:54 > 0:12:57Oh, dear. Aaargh!
0:12:57 > 0:12:58Aaargh!
0:12:58 > 0:13:02Aaargh! Aaargh!
0:13:02 > 0:13:05Guys! Guys! I know what we need.
0:13:05 > 0:13:07- We need a fan.- Oh.
0:13:07 > 0:13:12A fan sucks up molecules from behind and pushes them out the front.
0:13:12 > 0:13:15So if we use a fan for our apple scrumper, it will suck up the air
0:13:15 > 0:13:18and the apples, and we can deposit them in the washing area.
0:13:18 > 0:13:23Brilliant. By the way, Ed, this parcel just arrived for you.
0:13:23 > 0:13:25Oh, right, I see.

0:13:27 > 0:13:30Guys, I know what you've done.

0:14:27 > 0:14:31and I sent it to you to laugh at, because it's so...stupid.
0:14:31 > 0:14:35No, of course our invention is going to be better than that.
0:14:35 > 0:14:37No, no, we're making the apple scrumper.
0:14:37 > 0:14:40It's a machine that sucks up apples and then it washes them
0:14:40 > 0:14:44and it chops them and then you put them into pies.
0:14:44 > 0:14:45You love apple pies?
0:14:45 > 0:14:48I mean, yes, you love apple pies!
0:14:48 > 0:14:50Which is why we're making it, for your birthday.
0:14:50 > 0:14:54Yes, we're going to give you a pie. Lovely, so...
0:14:54 > 0:14:58It's going very well, actually. So we're going to get on with it now.
0:14:58 > 0:15:00Love you... I mean, bye.
0:15:01 > 0:15:05OK, right, we're under serious pressure now.
0:15:05 > 0:15:06She really wants a pie.
0:15:06 > 0:15:08Come on, let's make it!
0:15:21 > 0:15:22Oh, yes.
0:15:22 > 0:15:24Wilf, come over here.
0:15:26 > 0:15:29We've made some serious adjustments to your apple scrumper.
0:15:29 > 0:15:32We've rebuilt the body, got a fan to suck up the apples.
0:15:32 > 0:15:34It'll ride at a nice leisurely pace now.
0:15:34 > 0:15:37- Do you want to see it?- Yep. - OK, here it is!
0:15:38 > 0:15:42- Ha, ha, ha! Das da mummy. Ha, ha, ha! - Yeah, it's not my mum.
0:15:42 > 0:15:44Hilarious. Let's get rid of that.
0:15:44 > 0:15:48That's obviously yours.
0:15:48 > 0:15:50Wilf, take a seat.
0:15:51 > 0:15:54Strap you in here.
0:15:54 > 0:15:58Don't want you to get blown off your seat by...
0:15:58 > 0:16:00this that I've got hiding under here.
0:16:02 > 0:16:04The fan!
0:16:04 > 0:16:09This is going to suck all the apples up into this bucket here.
0:16:09 > 0:16:11Right, shall we give it a test run?
0:16:11 > 0:16:12- Yeah.- Are you ready, Wilf?- Yeah.
0:16:12 > 0:16:15- I said are you ready, Wilf?!- Yes!
0:16:15 > 0:16:18Right, OK, let's start the fan.
0:16:20 > 0:16:23Is it working? Yes, brilliant.
0:16:23 > 0:16:26OK, I've got some apples here in this bowl, fresh from the orchard.
0:16:26 > 0:16:29The fan's going at full speed now.
0:16:29 > 0:16:32Let's start scrumping!
0:16:35 > 0:16:37It doesn't seem to be sucking all the apples.
0:16:37 > 0:16:39Some of them are being a bit stubborn.
0:16:43 > 0:16:45Hmm.
0:16:46 > 0:16:48- Ah?- Oh.
0:16:48 > 0:16:51- It's only leaves and twigs. - There's no apples.
0:16:51 > 0:16:54It's sucking up all the small stuff but not the big stuff.
0:16:54 > 0:16:57That's not very fair. What have the apples done to deserve that?
0:16:57 > 0:16:59Why is the fan not working?
0:16:59 > 0:17:03- OUCHO SPEAKS CACTINIAN - You know all about fans?
0:17:03 > 0:17:06OUCHO SPEAKS CACTINIAN
0:17:06 > 0:17:09- CHANTING: - Oucho! Ouch! Oucho! Oucho!
0:17:11 > 0:17:14No, no, no, not those type of fans.
0:17:14 > 0:17:16- Huh?- The other type of fan.
0:17:16 > 0:17:18Oh, di.
0:17:18 > 0:17:23- Yes. So you haven't got a story about that, have you?- Di, I doss.
0:17:23 > 0:17:25- Really?- Di, I doss.
0:17:25 > 0:17:27- And it's true, is it?- Mm-hm.
0:17:27 > 0:17:31- Wilf, do you think we should let him tell his story?- Yes.- Really?
0:17:31 > 0:17:33Yes.
0:17:33 > 0:17:34Go on, then.
0:17:36 > 0:17:39OUCHO SPEAKS CACTINIAN
0:17:39 > 0:17:42And not that type of fan, either!
0:17:42 > 0:17:46I meant an electrical fan! You know, like the one on the apple scrumper?
0:17:46 > 0:17:49Oh, di!
0:17:49 > 0:17:53You haven't got a story about that one. No, I didn't think you did.
0:17:53 > 0:17:58Can we stop wasting time and think about this apple scrumper, yeah?
0:17:58 > 0:18:00How are we going to make it work?
0:18:00 > 0:18:03- Fix it? - Oh, yeah, nice one, genius boy(!)
0:18:03 > 0:18:06How are we going to get the apple scrumper working?
0:18:06 > 0:18:09I know. Let's ask Marcel Le Shoosh.
0:18:11 > 0:18:15Hello, Marcel. We were wondering if you could tell us something.
0:18:15 > 0:18:17Oh, that's right, yes, yes, yes.
0:18:17 > 0:18:21You can't speak. Could you show us through the medium of mime?
0:18:21 > 0:18:25Great. How can we suck up apples?
0:18:25 > 0:18:27Oh, what's he doing?
0:18:27 > 0:18:29Your chips are too hot?
0:18:31 > 0:18:35Um, you've got an appalling sense of balance? You've got wind?
0:18:35 > 0:18:38What are you saying?!
0:18:40 > 0:18:42OUCHO SPEAKS CACTINIAN
0:18:42 > 0:18:47He's saying that the size and speed of the fan determines how many molecules it moves?
0:18:47 > 0:18:50Hang on, I need to write this down.
0:18:52 > 0:18:56Right, so the larger the fan or the faster it rotates, the more
0:18:56 > 0:19:00air pushes forward, which means the more air it sucks from behind.
0:19:00 > 0:19:04So a faster-rotating fan will suck up more air?
0:19:04 > 0:19:06Oh, great.
0:19:06 > 0:19:10But how can we find out how big or fast the fan needs to be to suck up apples?
0:19:10 > 0:19:11Di.
0:19:11 > 0:19:15Um, we need a fan...resting machine?
0:19:15 > 0:19:17Noss, noss, noss.
0:19:17 > 0:19:20- We need a fan nesting machine?- Noss.
0:19:20 > 0:19:22What?!
0:19:22 > 0:19:24OUCHO SPEAKS CACTINIAN
0:19:24 > 0:19:26Oh, we need a fan TESTING machine.
0:19:26 > 0:19:29Why didn't you say?
0:19:29 > 0:19:32Oh, oh, you've got one here.
0:19:33 > 0:19:35- Thanks, Marcel!- Oh, di.
0:19:36 > 0:19:38PHONE RINGS
0:19:39 > 0:19:42Right, hurry up, Oucho, we've only got a day left.
0:19:42 > 0:19:43Di.
0:19:46 > 0:19:47Oi!
0:19:51 > 0:19:54That's bigger than I thought it was going to be.
0:19:54 > 0:19:56So, Wilf, do you know what this is?
0:19:56 > 0:19:59A fan speed-testing machine?
0:19:59 > 0:20:01Oh, well-read.
0:20:01 > 0:20:03Yeah, it is.
0:20:03 > 0:20:06- This tube here attaches to a fan, right?- Mm-hm.
0:20:06 > 0:20:09That feeds into another tube. If there's something in this tube,
0:20:09 > 0:20:12it either gets sucked up by the suction from the fan,
0:20:12 > 0:20:15or, if that's not strong enough, it falls out.
0:20:15 > 0:20:18I've got fans here of different sizes and speeds.
0:20:18 > 0:20:22So we've got the office fan, the portable vacuum cleaner,
0:20:22 > 0:20:27hairdryer, the big vacuum cleaner. Sit there and report the findings.
0:20:27 > 0:20:29Am I going to have apples dropped on my head?
0:20:29 > 0:20:31No, no, not apples,
0:20:31 > 0:20:35because the BBC health and safety department wouldn't allow that.
0:20:35 > 0:20:38So we found something that's the same weight as apples.
0:20:38 > 0:20:39It's these balloons here,
0:20:39 > 0:20:45- filled with custard.- I have a feeling this is going to get messy.
0:20:45 > 0:20:48- It's not going to get messy, is it, Oucho?- Noss, noss, noss.
0:20:48 > 0:20:50OK, right. Let's get testing, shall we?
0:20:50 > 0:20:54- OUCHO SPEAKS CACTINIAN - Oh, yeah, good idea.
0:20:54 > 0:20:58Wilf, we're going to make you wear Oucho's special hat.
0:20:58 > 0:21:01The fan's on. Just got to feed this balloon in,
0:21:01 > 0:21:05- and let's see if it's got enough suction.- Go!
0:21:08 > 0:21:11How do you think the suction was on that first fan, Wilf?
0:21:11 > 0:21:13- Not very good.- No, it wasn't.
0:21:13 > 0:21:17We won't use an office fan. But I've got the portable vacuum cleaner.
0:21:17 > 0:21:20This could be just the ticket. Right, lots of lovely suction now.
0:21:20 > 0:21:23I'm sure you won't get any more custard on you!
0:21:23 > 0:21:25- Are you sure?- Absolutely sure!
0:21:29 > 0:21:34Oh, dear. What do you think of that?
0:21:34 > 0:21:36- Rubbish.- Rubbish.
0:21:36 > 0:21:40Right, hairdryer next, cos it sucks air in at the back.
0:21:40 > 0:21:43I think it's going to be a bit better. It might work, it might not.
0:21:43 > 0:21:47Yeah, well, it is stronger, so you might be custard-free.
0:21:47 > 0:21:50Who knows? All right, Wilf? Pay close attention.
0:21:50 > 0:21:53Let's see what this hairdryer's suction is like.
0:21:57 > 0:21:59HE LAUGHS AND SQUEALS
0:22:00 > 0:22:03Right. So, Wilf, we tried the hairdryer.
0:22:03 > 0:22:05What do you think of that?
0:22:05 > 0:22:08- It didn't go very well.- No.
0:22:08 > 0:22:11Well, this is the last thing we've got left, the big vacuum cleaner.
0:22:11 > 0:22:13So let's hope that this works.
0:22:16 > 0:22:18Here we go, Wilf. Good luck.
0:22:24 > 0:22:27Whoa! That's it! That's all we need!
0:22:27 > 0:22:29Yahoo!
0:22:29 > 0:22:35So, Wilf, my custardy friend, what did we find out there?
0:22:35 > 0:22:39That we need a fan as big and fast as the vacuum cleaner.
0:22:39 > 0:22:41Yes, spot on. We've got the custard.
0:22:41 > 0:22:43Let's make those apple pies, come on!
0:22:53 > 0:22:56# This week I have come up with my own invention
0:22:56 > 0:22:59# A present for the Big Big Cheese was my intention
0:22:59 > 0:23:04# I was so delighted with myself I chose the apple scrumper
0:23:04 > 0:23:05# Designed by Wilf
0:23:05 > 0:23:09# A moving machine that could suck up an apple
0:23:09 > 0:23:12# How would that work? I was completely baffled
0:23:12 > 0:23:15# Benson filled us in, that fish ain't no fool
0:23:15 > 0:23:18# It's all about air pressure and molecules
0:23:18 > 0:23:21# Filling the empty space creates
0:23:23 > 0:23:24# Suction
0:23:24 > 0:23:29# Our apple scrumper could now go go into
0:23:29 > 0:23:31# Production
0:23:34 > 0:23:37# We turned a box upside-down and fixed on a tube
0:23:37 > 0:23:40# It didn't suck at all, didn't even move
0:23:40 > 0:23:43# A fan would remove the air, said Scott Stuck
0:23:43 > 0:23:47# The front of a fan blows behind it, sucks
0:23:47 > 0:23:49# We dealt with the fan, had another try
0:23:49 > 0:23:53# It only picked up leaves, they don't taste good in a pie
0:23:53 > 0:23:56# Marcel said try a fan with a faster rotation
0:23:56 > 0:24:01# I say, "said", it wasn't strictly a conversation
0:24:02 > 0:24:04# A fan speed-testing machine
0:24:04 > 0:24:08# Was what we... Desired
0:24:08 > 0:24:12# We got one and now we know what speed is...
0:24:13 > 0:24:18# ..Required-ahhh! #
0:24:19 > 0:24:25- Well, here we are in a beautiful orchard. Good choice of Wilf's.- Who?
0:24:25 > 0:24:28- Wilf.- Wha'?- Don't pretend you don't know who Wilf is.- Oh, di.
0:24:28 > 0:24:30OUCHO SPEAKS CACTINIAN
0:24:30 > 0:24:32No, not my dad. You've met my dad.
0:24:32 > 0:24:35He's not called Wilf, is he? Wilf!
0:24:35 > 0:24:39- Wilf!- Aargh! Aaargh!- No, not "wolf".
0:24:39 > 0:24:41Wilf! Him.
0:24:41 > 0:24:44- Oucho, you know who I am.- Oh, di.
0:24:44 > 0:24:48Sorry about that. I know we've been working with you for three days.
0:24:48 > 0:24:50Don't take offence. Um... Oh, now look.
0:24:50 > 0:24:53This always happens when you're making TV. The autograph hunters...
0:24:53 > 0:24:57Actually, they've probably heard we're making apple pies.
0:24:57 > 0:24:59They're pie stealers. I'll sort this out. Oi, you lot!
0:24:59 > 0:25:03I know what you're up to with your plates and your bowls,
0:25:03 > 0:25:07and you can't have any, you pie stealers! Go on, get out of it, clear off!
0:25:08 > 0:25:10Ed, that's my family.
0:25:10 > 0:25:12Oh.
0:25:12 > 0:25:14Oh, hello.
0:25:14 > 0:25:15- Losserly.- Sorry.
0:25:15 > 0:25:17Just going to do the unveiling.
0:25:17 > 0:25:19Let's get on with it.
0:25:19 > 0:25:24So Wilf asked us to build him an apple scrumper, a machine that would suck up apples,
0:25:24 > 0:25:29- wash them and chop them so he could make some lovely apple pies. Shall we show them at home?- Yeah.
0:25:29 > 0:25:31Here it is!
0:25:32 > 0:25:37No, not really. You can't suck up many apples with that! Here it is.
0:25:43 > 0:25:47So, Wilf, why don't you tell everyone about your apple scrumper
0:25:47 > 0:25:49whilst I have a lovely cup of tea?
0:25:49 > 0:25:52Well, the apples get sucked up this tube by this fan here.
0:25:52 > 0:25:56They go down here, then I open this hatch,
0:25:56 > 0:25:58where they fall into this bowl.
0:25:58 > 0:26:04I pick them up, put them into this tube and these jets suck up water
0:26:04 > 0:26:08from down here and then wash the apples, then they go down this tube
0:26:08 > 0:26:13and get chopped up in here by the rotating blades
0:26:13 > 0:26:18and then the apple pieces fall into this bowl so I can make apple pie.
0:26:18 > 0:26:20Do you want to do all my presenting for me?
0:26:20 > 0:26:23You're great. Right, let's start getting these apples.
0:27:05 > 0:27:07Oh, losserly.
0:27:08 > 0:27:12Well, Wilf, I thought that was 100% success.
0:27:12 > 0:27:15Not only does the apple scrumper suck up apples, but it washes them
0:27:15 > 0:27:19and chops them and they taste delicious in this pies. Mmm.
0:27:19 > 0:27:23- Did you have fun?- Yep. - What was the best bit?
0:27:23 > 0:27:25I think driving the apple scrumper.
0:27:25 > 0:27:27Oh, di.
0:27:27 > 0:27:30Well, that was good. The Big Big Cheese will be so pleased
0:27:30 > 0:27:34we made the apple scrumper and made all those pies for everyone to eat.
0:27:34 > 0:27:38Especially as they were so delicious. We polished off every last one of them.
0:27:38 > 0:27:42- OUCHO SPEAKS CACTINIAN - Indeed, not a single crumb left.
0:27:42 > 0:27:44Oh, except for the pie I put in the van
0:27:44 > 0:27:47- that we're sending to her for her birthday.- Wha'?
0:27:47 > 0:27:50- The extra pie I left in the van for no-one to eat.- Oh.
0:27:50 > 0:27:51I left it on your seat.
0:27:51 > 0:27:54- Hang on, where's it gone?- Ah, buh...
0:27:54 > 0:27:58- Oucho, you didn't eat it, did you? - Noss.- Did you?- Noss.- Did you?- Noss.
0:27:58 > 0:28:00- Did you?- Noss.- Did you?- Di.
0:28:00 > 0:28:03Argh! We've got to get the apple scrumper working again
0:28:03 > 0:28:07- before we get the sack! You flunk! - You're a flunk.- You're the flunk!
