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.
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 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)
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: 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)
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)
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.
