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 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.
Deliberate mistake: Andy is watching TV, when Bruce (presenter of Bruce's price is right) is calling out for contestants he shouts out three names (Helen Hunt, Akshai Vikoria and Andy Pipkin). However, when we see the contestants - there are four and Bruce says "You are the first four contestants on the price is right" even though only three people were called out. (00:06:55)
