Fortified with the outrageous humor that made classics out of Animal House and Vacation, National Lampoon's trilogy of hilarious spoofs pokes fun at everything from marital strife to serial killers. The laughs keep coming as a husband and wife take separate vacations; a fed-up stripper seeks revenge on her enemies; and two mismatched cops track a killer. Peter Riegert, Diane Lane, Robert Culp, Richard Widmark and Robby Benson star.
