Revealing mistake: When Cheech and Chong are parked in their car smoking a joint, the car is filled with smoke. The smoke must come from a smoke machine outside as it is moving around very fast as if blown by the wind. (00:13:25)

Sgt. Stedenko: The only kind of meat a priest could eat on Friday was nun.

Curtis: This shit is so bad, it'll put a hump on a camel's back.

Border Guard: So, how long you've been in Mexico?
Pedro: A week. I mean a day.
Border Guard: Well, which is it? A week or a day?
Pedro: A weekday.

Question: During the Battle of the Bands near the end of the film, a band with a singer who sounds like and somewhat resembles Joey Ramone performs a song called "So Socko" (or possibly "So Psycho"). I've heard some people insist that it was, in fact, Joey Ramone in an uncredited role, but it doesn't really look like him and doesn't have Joey's stage presence, i.e, standing still throughout the performance as opposed to moving about the stage. So who was the actual singer for this particular band?
