Revealing mistake: There are numerous shots where "Avid"s ginger hair can be seen coming out of the masks.
Continuity mistake: In the Michael Jackson "Psychotherapy Day" sketch, Michael is leaning forward (or to the side depending on how you look at it) with his arm on the desk but in the closeups he is sitting up, arms by his side.
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.
