If Mel Brooks can be credited (and blamed) for tarnishing the silver screen with flatulence, the creators of "Animal House" must therefore be held responsible for all the teen "gross-out" comedies to follow. 

As is often the case, however, "Animal House" is vastly better than the majority of its successors — a fresh emission, rather than a stale one. The final sequence, which reveals the later fates of all the film's characters ("Senator and Mrs. John Blutarsky"), is enough to send anyone into "double-secret" spasms of laughter.
