Favorite comedies:
High Anxiety with Mel Brooks - makes fun of psyhology and Alfred Hitchcock movies.
It's a Mad, Mad, Mad, Mad World - has about a dozen top comics in it.
Any movie with the Marx Brother or WC Fields in it.
My Cousin Vinnie with Joe Peschi - two boys convicted of a crime and represented in court by an incompetent lawyer who is saved by his girl friend's expert testimony.
Good Morning Vietnam with Robin Williams - based on a true story, very funny Robin Williams dialogue.
Home Alone
There are several others, but I can't think of the titles, I'll be back later.
I think that if they ever turn them into a movie, "Studies in the Scriptures" by Charles Taze Russell would make a great comedy.
