I'll take the Rabbit. This movie is what was supposed to be the third part of the Chinatown series, but it never materialized. This movie has it all: Comedy, mystery, drama. It has it all, including the smoking hot babe Jessica. As a cartoon fan, seeing Bugs and Mickey on screen at the same time is orgasmic at least.
Caddyshack is great too. It is the parody of sports movies, period. Golf, more than any other sport, needed to be parodied. Bill Murray and Chevy Chase own this movie with their stuff. Even still, I'll take Roger for its impressive performances. The humans were talking to nothing when they talked to the cartoons. That's just difficult to do.
