Favorite Harold Ramis/Bill Murray movie

Harold Ramis?

While I know the he either helped write and/or directed... some/all?... of these films... I can only vote for the ones where he had a major roll in it...

1.) Ghostbusters
2.) Stripes
3.) Ghostbusters II



While I love Groundhog Day, Harold Ramis was only in it for one very short scene.

If he was in Caddyshack, then I keep missing it.
