What is your favorite Michael Keaton movie?

I like almost all of his movies: Beetlejuice, Multiplicity, Batman, Mr. Mom etc. but my favorite will always be The Dream Team. It's about 4 nutcases who get lost in N.Y. on their way to a Yankee game when their therapist gets mugged. It stars Michael Keaton as an imaginitive maniac, Christopher Lloyd as a terribly annoying O.C.D. guy, Peter Boyle who thinks he's Jesus, and Stephen Furst who's a nearly catatonic vege.
