Question: Can anyone explain to me the scene in which Wayne is pulled over by a cop and shown a picture? I know it's supposed to be funny, but I don't get the joke.
Answer: You presumably haven't seen Terminator 2. The actor playing the cop is Robert Patrick, who played the shape-shifting T-1000 in that movie, who masqueraded as a policeman for most of the film. The T-1000's mission was to track down and terminate a boy - hence the "have you seen this boy" line that he says to Wayne.
Answer: There was a series of commercials for a mustard called Grey Poupon in the late 80s and early 90s. It usually involved someone driving up next to a limo in a cheaper car, rolling their window down and asking them "pardon me sir, do you have any Grey Poupon?". Then the richer man in the limo would say "certainly" and pass it to the guy in the other car. They were incredibly stupid commercials and wayne's world makes fun of them.
