National Lampoon's Animal House (1978)

Faber College has one frat house so disreputable it will take anyone. It has a second one full of white, anglo-saxon, rich young men who are so sanctimonious no one can stand them except Dean Wormer. The dean enlists the help of the second frat to get the boys of Delta House off campus. The dean's plan comes into play just before the homecoming parade to end all parades for all time.—John Vogel
