Revealing mistake: When Vyvyan is trying to show off his finger trick there are two mistakes, 1) the fingers are bent the other way (this shows that the hand is fake), 2) when he cuts off the wrong finger there is blood shooting out but you can see the tube of blood right near his wrist.
Visible crew/equipment: When the seriously injured chip is voicing her last words to the carrot, the wire moving her is painfully obvious coming in from the bottom right of the screen. Immediately after that we zoom in on the carrot and can easily see the wire moving it too.
Revealing mistake: When Ftumch hits Saunders, some of Ftumch's red make-up rubs off onto Saunders' face.

Revealing mistake: The guys turn on the TV and discover the channels don't work. When Rik changes the channels, he leans in front of the TV hiding the screen. This is because the 'channel' never changes at all - it's just a picture stuck onto the TV. You can see this when the camera rotates around, just before the screen goes out of view, behind Rik. (00:09:43)

Visible crew/equipment: When the main characters realise the bomb has been set off, there is a shot with all four characters in the frame, and a loud ticking sound is heard. The boom mic can be seen at the top of the frame when this happens. (00:33:15)
Revealing mistake: Near the start, when Vyvyan sticks his hand through the wall to swear at Rick, you can see where the holes from previous takes have been papered and painted over.
Revealing mistake: When Neil is about to blow up the kettle, watch as he plugs it in. The power point moves a bit.

Visible crew/equipment: When Rick talks to the Christian woman, there is one shot showing the stairs behind her. In the upper right corner of the screen you can see someone's legs as he walks out of sight. None of the characters should be there at that precise moment. (00:06:55)

Visible crew/equipment: When the two female party guests walk over to the giant sandwich that has been modified into a chair, a boom mic can be seen at the top of the frame, dipping into shot. (00:12:23)

Visible crew/equipment: When Neil has a smoke that his hippy friend gave him, he floats up into the sky, and you can see the strings lifting him up.

Revealing mistake: When Rik Mayall is in the middle of the doorway dancing to the Human League record, you can see him abruptly change his dance steps and deliberately move across to his left (our right) to give the two Police officers room to get past him to destroy the record player. He had his back to the front door the whole time and wouldn't have been able to see them come in.

Continuity mistake: Vyv has a beer when he enters the 'party', but when he starts doing exercises in a vain attempt to impress the girls, it's gone. He had no time to throw it away.

Revealing mistake: When Rick realises his bedroom is on fire, he opens a window to allow water from a flood to come into the room and put the fire out. When the fire dies out as it gets covered in water, a digital red cloud can be seen around the fire as it goes out, revealing that the fire was a digitally added effect. (00:20:23)

Revealing mistake: The neighbourhood outside Rick's window is flooded and completely covered in water. When he opens the window and water comes into the room, the water shown outside the window appears to be a dark blue colour. But once Rick closes the window, the water switches to a light teal colour midway through the shot, revealing that the water is a digital green screen effect. (00:20:24)

Continuity mistake: When Rick closes the window after putting out the fire, there is a small fire behind his bed that hasn't been put out. Vyvyan then walks into the room and the fire behind his bed is suddenly out. Also, the bottom of the curtain next to the bed suddenly moves onto the windowsill in between the two shots. (00:20:27)

Revealing mistake: When Neil points to the window after saying he hates sharks, Vyvyan says, "That's just the most completely brilliant thing I've ever seen," whilst sharks are swimming past the window. Just as Vyvyan finishes the line, there appears to be a visible cut on-screen shown around the window, where the sharks are swimming past, revealing the use of stock footage of sharks swimming that was digitally added over the window. (00:21:06)

Visible crew/equipment: When the landlord is about to start smashing holes in the door, a boom mic creeps into the top of the screen. (00:26:46)
Revealing mistake: When Jerzei is coming through the door with an axe, you can see the door is paper thin to make it easier to get through. In fact you can see Alexei Sayle being very careful to only chip small bits away because a decent whack with the axe would smash the whole thing down.
Continuity mistake: When Mike tells Neil to sit down, he turns his head to face him. When the shot cuts, he is suddenly looking down at his book. (00:04:53)






Chosen answer: It wasn't referring to anything real, just that the government's bureaucratic naming, The Guardian's mangled spelling or Rick's bad pronounciation resulted in the unlikely word "Footumch" being spoken.
