Episode One - S1-E1
Corrected entry: When Craig David is at the hair dresser's, after he has had his rows done, in the mirror in the background you can see the camera crew reflected.
Episode One - S3-E1
Continuity mistake: In the Blankety Blank sketch,the village people person holds up a board saying "gay" on it, but when it switches to the long shot showing all the characters, it has changed to "massive bender". ""Massive bender" is part of another sketch involving Blankety Blank, so it's an editing problem.
Trivia: Some masks are reused. For example the masks for Peter Parker, Trisha and Junan Pingpong were originally Leo DiCaprio, Michelle Williams and Question Rowland.
Correction: The 'Craig David' sketch is meant to be a documentary, so it does not matter if the cameras are visible.
