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.
Continuity mistake: In the scene where Daffyd tells his Mum and Dad that he is gay, his mum starts polishing his red belt, then irons an item of clothing. In the very next shot, however, the iron is resting on the ironing board, without her having time to put it down.
