0:00:02 > 0:00:04- Ready, Gnasher?- Gnesh! - Let's go!
0:00:04 > 0:00:08# Playing by the rules
0:00:08 > 0:00:11# Is highly overrated
0:00:11 > 0:00:14# Unstoppable, unstoppable, yeah!
0:00:14 > 0:00:17# They can't hold us back
0:00:17 > 0:00:21# We'll make the most of every second
0:00:21 > 0:00:24# Unstoppable, unstoppable, yeah!
0:00:24 > 0:00:26# After all is said and done
0:00:26 > 0:00:29# Shout, "One for all and all for fun!"
0:00:29 > 0:00:33# Nothing's going to bring us down today
0:00:33 > 0:00:35# Open up your eyes
0:00:35 > 0:00:39# The world outside is waiting. #
0:00:54 > 0:00:59All right, class, you have five minutes to finish today's experiment.
0:00:59 > 0:01:03With my personal junior genius lab kit,
0:01:03 > 0:01:07that should present no problem, Mrs Creature.
0:01:07 > 0:01:08He-he!
0:01:10 > 0:01:14Er, Mrs Creature? My beaker's broken. Look!
0:01:14 > 0:01:16Oh, yeah.
0:01:16 > 0:01:20Then pair up with Walter, Dennis. BOTH: WHAT?!
0:01:20 > 0:01:23Oh, surely you too can work together for five minutes.
0:01:23 > 0:01:26CLOCK TICKS
0:01:26 > 0:01:27Stop!
0:01:27 > 0:01:30EXPLOSION
0:01:30 > 0:01:34We've had to evacuate the entire school because of the smell.
0:01:34 > 0:01:37Do you have anything to say for yourselves for ruining
0:01:37 > 0:01:40- Mrs Creature's experiment? - Yes, headmaster.
0:01:40 > 0:01:42It was all his fault.
0:01:42 > 0:01:45I told you not to touch the beaker when the liquid oozes.
0:01:45 > 0:01:48You have zero understanding of slime production.
0:01:48 > 0:01:52What's there to understand? Puerile pranks, tawdry tricks.
0:01:52 > 0:01:55- All child's play.- Child's play?!
0:01:55 > 0:01:58Menacing takes skill and precision timing.
0:01:58 > 0:02:01You couldn't menace a dead fish!
0:02:01 > 0:02:03I could do that in my sleep.
0:02:03 > 0:02:06You wouldn't last one afternoon completing my to-do list.
0:02:06 > 0:02:10What? Measuring the straightness of my tie with a ruler.
0:02:10 > 0:02:13Yeah, really hard, Walter. I do more than that. I...
0:02:13 > 0:02:14Boys, boys, boys.
0:02:14 > 0:02:18It seems we have here a classic lack of mutual understanding,
0:02:18 > 0:02:20but I have the perfect solution.
0:02:20 > 0:02:24You will each spend this afternoon living each other's lives.
0:02:28 > 0:02:32I've spoken to your parents and it is agreed. This afternoon, you will live
0:02:32 > 0:02:35according to the habits and rules of the other's household.
0:02:37 > 0:02:38Stop!
0:02:38 > 0:02:41Swap!
0:02:41 > 0:02:43- Uh!- Ruh-ruh!
0:02:43 > 0:02:47I'll explain later, Gnasher. It's...complicated.
0:02:47 > 0:02:50Here is Walter's jam-packed schedule for this afternoon.
0:02:50 > 0:02:52Jingle Composer Club.
0:02:52 > 0:02:56Toothpick modellers' symposium with the Colonel.
0:02:56 > 0:03:01Competitive bird-watching? Swimming pool mathletics? Pet grooming?!
0:03:01 > 0:03:04CAT MEWLS, GNASHER CHUCKLES
0:03:04 > 0:03:06Where do you keep your garden shears?
0:03:08 > 0:03:13- Dennis's schedule? For what? - His after-school activities!
0:03:13 > 0:03:18He doesn't exactly have a schedule. He...lives in the moment.
0:03:18 > 0:03:21- HE LAUGHS - This will be a breeze!
0:03:21 > 0:03:22Just as I thought.
0:03:22 > 0:03:25I do hope Dennis is coping.
0:03:25 > 0:03:28CLASSICAL MUSIC
0:03:29 > 0:03:31THEY GROAN
0:03:31 > 0:03:34HE MAKES A RACKET
0:03:40 > 0:03:47- That's not...quite how... Walter does it.- No, it's not!
0:03:47 > 0:03:53Din-Makers, prepare for practice! I hope you've studied your chords.
0:03:53 > 0:03:56Stand straight, shoulders back, no slouching!
0:03:56 > 0:03:59THEY STRAIN
0:03:59 > 0:04:03Now, after me. I'll count us in.
0:04:03 > 0:04:08A-one, two, three, four.
0:04:08 > 0:04:11Um, usually Dennis just says something like, "Rock!"
0:04:11 > 0:04:14- Rock?- Don't mind if I do!
0:04:14 > 0:04:17THEY MAKE A RACKET
0:04:18 > 0:04:23Competitive bird-watching? Ohhh! Let's liven this up, Gnasher.
0:04:24 > 0:04:26Ahhh! Snake!
0:04:31 > 0:04:35This isn't the sort of thing we do with Dennis, Walter.
0:04:35 > 0:04:36Hmm...
0:04:39 > 0:04:42- But that is. - THEY LAUGH
0:04:45 > 0:04:47Ta-da!
0:04:47 > 0:04:50So, THIS is a toothpick modellers' symposium.
0:04:50 > 0:04:52Hmm... No...
0:04:52 > 0:04:56Playing with Bea can't be THAT hard.
0:05:01 > 0:05:03SHE STRAINS
0:05:05 > 0:05:07Ooh... Ooh, no...
0:05:07 > 0:05:10Ohh... I don't know how much more of this I can take!
0:05:10 > 0:05:15What's swimming pool mathletics anyway? Huh?
0:05:15 > 0:05:193 times 7 is 21, 4 times 7 is 28,
0:05:19 > 0:05:225 times 7... Dennis?
0:05:22 > 0:05:26Oh, I know this one! Cannonball!
0:05:28 > 0:05:31HE LAUGHS
0:05:31 > 0:05:34So far you're not doing very well at being Walter, Dennis.
0:05:34 > 0:05:40I knew you'd find my life too hard. Meanwhile, I'm blitzing yours!
0:05:40 > 0:05:43Tree house tidied, a study regime for Bea.
0:05:43 > 0:05:45I've even introduced the Din-Makers
0:05:45 > 0:05:47to the principles of classical harmony.
0:05:47 > 0:05:49That's not being a menace, Walter!
0:05:49 > 0:05:52That sounds like things you'd do. Epic fail.
0:05:52 > 0:05:54Boys, you have one more chance to live each other's life
0:05:54 > 0:05:56before the day is done or...
0:05:58 > 0:06:04..I'll pair you up in every class until the term ends.
0:06:04 > 0:06:09- BOYS:- 17 times 32 is 544,
0:06:09 > 0:06:1218 times 32 is 576.
0:06:15 > 0:06:18- 19 times 32 is...- Ribbit!
0:06:18 > 0:06:20WALTER WAILS
0:06:20 > 0:06:24OK, time for plan D, G and W.
0:06:24 > 0:06:28We need to help each other if we're going to get through the experiment.
0:06:28 > 0:06:30Very well. Listen carefully.
0:06:30 > 0:06:33After swimming pool mathletics, it's bath time.
0:06:33 > 0:06:37Make sure you use plenty of soap. Then it's afternoon tea.
0:06:37 > 0:06:41This is very important - you must use the scone fork.
0:06:41 > 0:06:46It's second from the right. Do NOT use the Battenberg fork!
0:06:46 > 0:06:48OK, but, Walter, you've got to think like a menace.
0:06:48 > 0:06:51Remember - fun is always just around the corner.
0:06:51 > 0:06:53POSTMAN WHISTLES
0:06:53 > 0:06:57Come, Claudius. We have menacing to attend to.
0:06:57 > 0:07:00And it's bath time for you and me.
0:07:00 > 0:07:02GNASHER GROANS
0:07:02 > 0:07:05- # Da, da-da-da, da-da... # - DENNIS CHUCKLES
0:07:05 > 0:07:09Lots of soap, eh? Low setting, I think.
0:07:09 > 0:07:11Gnesh, gnesh!
0:07:11 > 0:07:13GNASHER WHIRS
0:07:13 > 0:07:16Ha-ha!
0:07:16 > 0:07:21Right. Let's get you kitted out with some menacing equipment.
0:07:21 > 0:07:24- Ooh. Ooh!- Ooh...
0:07:27 > 0:07:29DENNIS SIGHS
0:07:31 > 0:07:35Right, Gnasher. All I have to do is get through the scone test
0:07:35 > 0:07:37and life goes back to normal!
0:07:37 > 0:07:39Gnesh!
0:07:41 > 0:07:43Um...er...
0:07:44 > 0:07:48Mm-hm, he certainly looks and smells the part.
0:07:50 > 0:07:52- MOBILE RINGS - Ooh!
0:07:52 > 0:07:56'Not the Battenberg fork! Use the second one!
0:07:56 > 0:07:59'The second one!'
0:07:59 > 0:08:00Ha!
0:08:00 > 0:08:01Good show.
0:08:06 > 0:08:09Just goes to show you CAN complete a successful experiment
0:08:09 > 0:08:14- without any mischief. A+ for you, Dennis.- Yes!
0:08:14 > 0:08:17But Walter still has to pass HIS test.
0:08:17 > 0:08:21Oh, Walter excels at everything he does!
0:08:21 > 0:08:23He'll be just fine, I assure you.
0:08:26 > 0:08:29I'm not so sure about that. Come on, Gnasher!
0:08:31 > 0:08:34POSTMAN HUMS
0:08:34 > 0:08:36Hmm...
0:08:42 > 0:08:46Oooh-oooh! Where are the instructions on this device?!
0:08:46 > 0:08:47HE COUGHS
0:08:47 > 0:08:52Too late anyway. Postman's way out of range now.
0:08:52 > 0:08:55- POSTMAN: Strangely quiet today. - Oh, no!
0:08:55 > 0:08:57I told you not to waste time arranging the pranks
0:08:57 > 0:09:00according to the Dewey decimal system.
0:09:00 > 0:09:03But they needed sorting out!
0:09:03 > 0:09:07- I've failed!- Maybe not.
0:09:09 > 0:09:12No! I... Oh... I couldn't possibly!
0:09:14 > 0:09:18- Ha-ha! But...I could!- Gnesh-gnesh!
0:09:18 > 0:09:20Hmm... Do it, Claudius!
0:09:20 > 0:09:21CLAUDIUS SNARLS
0:09:21 > 0:09:22THEN MUNCHES
0:09:22 > 0:09:25Ohh! Ohhhh!
0:09:25 > 0:09:27Walter!
0:09:35 > 0:09:38What are you doing... Atchoo! ..doing, Walter?!
0:09:38 > 0:09:40Being Dennis, sir.
0:09:40 > 0:09:45Hmm...yes, I...I suppose you are. Well, well done. Very good. Atchoo!
0:09:50 > 0:09:52Gnesh!
0:09:52 > 0:09:56So, what have you.... Atchoo! ..learned today, Walter?
0:09:56 > 0:10:00Well, that...having no rules can be somewhat liberating.
0:10:00 > 0:10:07- And you, Dennis? - Ah...well...I...learnt that...um...
0:10:07 > 0:10:11er...that everyone needs a bath sometimes?
0:10:11 > 0:10:13- Hm?- Mm, yes, I suppose they do.
0:10:13 > 0:10:15Congratulations, boys,
0:10:15 > 0:10:19you have successfully completed today's experiment.
0:10:19 > 0:10:20Yes!
0:10:24 > 0:10:27Er, would you care to join us for afternoon tea, headmaster?
0:10:27 > 0:10:32Thank you, Walter. I never say no to a scone!
0:10:32 > 0:10:37Whoa! Who knew bath time could be so much fun?! Follow me!
0:10:44 > 0:10:48Ha-ha! Genius wears a striped jumper!
0:10:48 > 0:10:49Gnesh-gnesh!
