Duckie: We don't have none of this stuff in the boy's room! Wait a minute! We don't got none of this... we don't got doors on the stalls in the boy's room, we don't have, what is this? What's this? We don't have a candy machine in the boy's room.
Trivia: Several actresses with bit parts in this film went on to bigger and better things. The English teacher is played by Margaret Colin ("Independence Day", "The Devil's Own"). Benny's snobby brunette friend in gym class is Gina Gershon, and the blonde girl eying Duckie at the very end is Kristy Swanson (credited as "Duckette").
