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 with the Prime Minister, when Sebastian brings over the chocolate fingers, a shot before he brings them over there is nothing on the table. When Sebastian puts them on the table suddenly a cup has appeared. He did not bring over a cup and put it on the table, just the plate.
Continuity mistake: In the sketch with Kenny Craig, just after his mother brings in the sugar, the pot of sugar is quite close to the cups of tea. However in the next shot when Kenny hypnotises her and makes her not watch Songs of Praise, the sugar pot is now further away from the cups of tea.
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.
Deliberate mistake: In the scene where Peter Andre and his producer watch the footage of the royal family, in the background you can see princess Diana and the queen mother who had both unfortunately passed away before Little Britain was made. They had to use the old footage but it is still a mistake.
Plot hole: In "Little Britain Abroad", Marjorie swaps places with another Fat Fighter from somewhere called "Rocksprings" in America. In the first episode, when Marjorie is pushed into a police car by the sheriff, it says "Miami Dade". However, in the second episode, the American Fat Fighter, Blanche, says that she is from Rocksprings, Texas, not Miami.
Continuity mistake: In the first Andy and Lou sketch, when Andy sees the intro to 'The Price Is Right', there is a cup in front of him. However in the next shot Lou brings one over and it is the same one in the same position as in the first shot. Obviously the second shot was filmed first.
