0:00:12 > 0:00:15Hello, I'm Robert Webb.
0:00:15 > 0:00:17Welcome to Great TV Mistakes.
0:00:17 > 0:00:21Now, I know what you're saying - "But people in telly don't make mistakes.
0:00:21 > 0:00:24"They're all perfect, like you, Rob."
0:00:24 > 0:00:26Not true. Everyone makes mistakes.
0:00:26 > 0:00:28You just called me Rob, for instance.
0:00:28 > 0:00:32And no-one but no-one calls me Rob unless I give them permission. Understand?!
0:00:32 > 0:00:35Don't worry. People in telly are just like you.
0:00:35 > 0:00:39They mess up. A crew member appears in the back of shot, a prop changes colour,
0:00:39 > 0:00:42someone commissions another series of My Family.
0:00:42 > 0:00:45Mistakes get made, and that's where we come in.
0:00:45 > 0:00:48We find these embarrassing errors and make a show out of them.
0:00:48 > 0:00:53Some people might call that schadenfreude. I just call it funny.
0:00:53 > 0:00:54Enjoy.
0:00:56 > 0:00:58Hey, Magnum's in Friends.
0:00:58 > 0:01:01Look at the size of the bloke. They're having to widen the shot to squeeze him in.
0:01:01 > 0:01:04A bit too wide, if you ask me.
0:01:04 > 0:01:10That is the edge of the set. Unless there's always been an enormous hole in Joey and Chandler's wall.
0:01:10 > 0:01:13In which case, why does everyone still use the door?
0:01:13 > 0:01:15Well, we had a table in college.
0:01:19 > 0:01:22It's Doctor Who, '70s-style. And problems with the TARDIS
0:01:22 > 0:01:25have forced him to get these alien builders in.
0:01:25 > 0:01:30See the alien builder on the left, keep your eyes on his feet.
0:01:30 > 0:01:32D'oh! That's torn it, literally.
0:01:32 > 0:01:36Light, too much light!
0:01:36 > 0:01:39Yeah, he's got his space boot caught under the Axminster. You idiot.
0:01:39 > 0:01:44I know what you're thinking, how's he going to get his foot out from under the carpet?
0:01:44 > 0:01:47Pick it up or just kick the carpet out of the way?
0:01:47 > 0:01:51And he... Yeah, he just kicks it out of the way. Nice one.
0:01:51 > 0:01:53Goddamn alien cowboy builders!
0:01:55 > 0:01:58The IT Crowd, and Jen's up on the top floor.
0:01:58 > 0:02:01I feel like I'm on top of the world.
0:02:01 > 0:02:03Well, the top floor anyway, which is...
0:02:03 > 0:02:05Floor 34.
0:02:05 > 0:02:06Yes, floor 34.
0:02:06 > 0:02:12- OK, where am I going? - All the way down to the basement.
0:02:12 > 0:02:15From floor 34. But, hang on.
0:02:15 > 0:02:19That lift's only got 31 buttons, meaning there's only 31 floors.
0:02:19 > 0:02:21This doesn't make any sense.
0:02:21 > 0:02:25I'm beginning to think these people don't take their pretend lift buttons seriously.
0:02:27 > 0:02:31A brilliantly silly sequence from Wonder Woman now, starring
0:02:31 > 0:02:33killer ape Gargantua
0:02:33 > 0:02:37and this bloke in specs, who kicks off a classic dust-up
0:02:37 > 0:02:41by throwing a balsawood coffee table like a massive girl.
0:02:41 > 0:02:47Then, after some more "acting", he goes running for the door and that large red emergency button.
0:02:47 > 0:02:53Gargantua throws a poorly constructed dummy across the room and, hey, it's a military rozzer.
0:02:53 > 0:02:58He tries to press the button, misses it, but it goes off anyway. He's out of the game.
0:02:58 > 0:03:01But here comes his mate, who's elderly.
0:03:01 > 0:03:04He ignores the emergency button, cos it's not there any more,
0:03:04 > 0:03:07and bounces off Gargantua like a septuagenarian pinball.
0:03:07 > 0:03:10Yes, there was an error there but I'll be damned if I could spot it.
0:03:12 > 0:03:15Here's pathologist turned serial killer, Dexter,
0:03:15 > 0:03:18examining a dead body. Now, hold it there.
0:03:18 > 0:03:21Time check. 11 minutes past 4.
0:03:21 > 0:03:23And play.
0:03:23 > 0:03:26Dexter takes a quick shufti at the cadaver.
0:03:26 > 0:03:29And hold again. Ooh, it's 4:17.
0:03:29 > 0:03:31That little look took six minutes.
0:03:31 > 0:03:35Doesn't time fly when you're sniffing at a corpse.
0:03:39 > 0:03:40Here's Lucy Lawless as Xena
0:03:40 > 0:03:44in the best fighting form of her life, taking on baddie Deiphobus
0:03:44 > 0:03:47Go, Xena! She's hard as a rock.
0:03:47 > 0:03:49In fact, much harder than a rock.
0:03:49 > 0:03:51Especially THAT rock. Boing!
0:03:54 > 0:03:55Doing!
0:03:55 > 0:03:59Hmm, did they have foam in ancient Greece?
0:04:01 > 0:04:05That was the one I was trying to get a look at, not that Australian hayseed.
0:04:05 > 0:04:08'All's not well at Fawlty Towers, for a change.
0:04:08 > 0:04:13'Try as he might, Basil just can't get through to wife Sybil, for a change.
0:04:13 > 0:04:18'She's so annoyed and slams the door, along with half the wall.
0:04:18 > 0:04:21'That is some very unstable brickwork. Will somebody please call a builder?
0:04:21 > 0:04:24'And not Mr O'Reilly. Little joke for the fans there.'
0:04:26 > 0:04:32Will Smith is living it up in his uncle's mansion, a cardboard mansion.
0:04:32 > 0:04:34Boom, shake the room!
0:04:34 > 0:04:36I hope that's not a supporting wall.
0:04:41 > 0:04:43Right, they leave me no choice.
0:04:43 > 0:04:46A classic Thunderbirds car chase.
0:04:46 > 0:04:51Watch what happens when the baddies' car spins off the road.
0:04:51 > 0:04:52Timber!
0:04:52 > 0:04:56Either the biggest squirrel in the world is in those trees
0:04:56 > 0:04:59or the set guy just ran out of glue.
0:04:59 > 0:05:02I think he makes half of it up.
0:05:02 > 0:05:08Doctor Who's been on the telly for 47 years and 42 of those have been spent in corridors.
0:05:08 > 0:05:12That's because corridors are cheap and impossible to get wrong, mostly.
0:05:12 > 0:05:14Freeze the shot.
0:05:14 > 0:05:17Notice the sign on the left for Torchwood.
0:05:17 > 0:05:21Now, spin forward, and it's Billie's turn to try and fill some airtime.
0:05:22 > 0:05:26That's it, Billie, create a bit of tension. Keep the dads watching.
0:05:26 > 0:05:27And look at that.
0:05:27 > 0:05:32The sign's gone all bigger with loads of added signery that just wasn't there a moment ago.
0:05:34 > 0:05:40"Will the set designer please report to base where an arse-kicking is waiting? Thank you."
0:05:44 > 0:05:47You think you can kill a cop and get away with it?
0:05:47 > 0:05:49Why not? I've done it before.
0:05:49 > 0:05:51Star Trek: The Next Generation,
0:05:51 > 0:05:57and Captain Picard and Data have got all mixed up with some '30s gangster types on the holodeck.
0:05:59 > 0:06:02Meanwhile, outside in the corridor, we can clearly see there's
0:06:02 > 0:06:06absolutely no second corridor leading off to the side.
0:06:06 > 0:06:11Except when the gangsters step outside, there is.
0:06:11 > 0:06:15In space, no-one can hear you scream, "That was rubbish!"
0:06:17 > 0:06:19But what I said was a statement of fact.
0:06:19 > 0:06:22I won't condone theft, but everyone knows it's traditional
0:06:22 > 0:06:26when checking out of a hotel to snatch a towel.
0:06:26 > 0:06:32But apparently in deep space it's equally common when being discharged from sick bay, to nick a pillow.
0:06:32 > 0:06:34Two pillows in this shot,
0:06:34 > 0:06:36one pillow in this.
0:06:36 > 0:06:38Don't play the innocent with me, young man.
0:06:38 > 0:06:41I know what you're hiding in your space trousers.
0:06:43 > 0:06:46- It's not going to work. - Excellent, John, you're evolving.
0:06:46 > 0:06:52Here's one for fans of Lost, assuming there are any left.
0:06:52 > 0:06:56In this scene, Locke is required to throw a plastic tray at a stone wall,
0:06:56 > 0:06:59but see how the plastic tray makes the stone wall tremble.
0:07:01 > 0:07:05Normally, I'd say that was a TV mistake but this is Lost,
0:07:05 > 0:07:08so you know, anything's possible. I blame the polar bears.
0:07:10 > 0:07:14Hi, just so you know, we didn't mean...
0:07:14 > 0:07:17Back to Friends, which was, of course, always filmed in front of
0:07:17 > 0:07:20a live studio audience, and a very wobbly set.
0:07:22 > 0:07:26Hmm, about as convincing as that bloke's beard.
0:07:28 > 0:07:30Merry Christmas!
0:07:30 > 0:07:33This is an episode of Friends called The One With The Self-Opening Door.
0:07:33 > 0:07:35Oh God, you're the best!
0:07:35 > 0:07:37Door closed...
0:07:39 > 0:07:46Door open. If that isn't final proof of the existence of the supernatural, I don't know what is.
0:07:49 > 0:07:55Ronnie Barker in the excellent Porridge and the inmates of Slade are out
0:07:55 > 0:07:58for the day, under the supervision of Mr Barraclough in an old church.
0:07:58 > 0:08:04Well, the outside bits were filmed in an old church, but the interiors certainly weren't.
0:08:04 > 0:08:08Want proof? Just look what happens when Melvyn leans on a column.
0:08:08 > 0:08:13Yes, it wobbles in a way that most Saxon stonework just doesn't.
0:08:19 > 0:08:21Thanks to all of our contributors for being so sloppy.
0:08:21 > 0:08:25It's a good job it's telly and nothing more important, like a paper round,
0:08:25 > 0:08:29otherwise you'd have been fired. Bye-bye!
