Continuity mistake: In the Daffyd sketch, Daffyd has two nipple piercings. As those other gay men come through the door and he pushes them back, his right nipple ring has moved up his body - obviously a clip on. It stays there for a few moments, until the next shot where it's back on his nipple, with no time to put it back on.
Continuity mistake: In the sketch where Lou is about to paint Andy's bedroom, in the first wide shot, as Lou picks up the red paint, there is a paint tray, with two rollers and two brushes in it. Then when it cuts, the two rollers are now laying on the floor, and aren't in the tray.
Continuity mistake: In the Matthew Waterhouse sketch with the board games, he starts to play "Milk Round" and he has tipped many items on the table including a green circle sharpener. It is over by the pencil tin in wide shots but in close shots it is near the salesman's arm.
