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.
Question: It seems like there's some stuff cut out of the scene where Wayne and Garth meet the cop outside the donut shop. He stops them for some unsaid reason, then flips a coin at the end. What does any of this mean? Does he just get charmed and distracted by them?
Answer: It was just establishing that Wayne and his crew were friendly with Officer Koharski. They cut their conversation short because they were afraid Phil was about to throw up and needed to get him a cup of coffee.
Before Phil gets sick, they're just having a conversation. After it cuts from Phil, Koharski is suddenly holding a quarter in between his fingers. There seems to be a scene cut before they see Phil get sick to explain where the quarter came from. (Like if I had to guess, does Koharski pull out the quarter to show what he found in the cavity search?) That's what the question is asking, not is there a scene cut after Phil gets sick to explain why Koharski just walks away.
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.
