what is your favorite comedy classic movie of all time?

I would have to say mine is Caddy Shack. That is a classic with lots of great actors in it. The only thing that ruined it was that they tried to make a caddy shack 2 and it was terrible. I like comedies and there are lot I like but this one is one of my all time favorites.

according to me All the movies played by charlie was morvalas. I love charlie.

There are so many good classic movies. I would say one of my favorites is the Great Outdoors, with John Candy.

Half Baked was hot yeah! Beverly Hills Cop with young Eddie, What About Bob?, and Young Frankenstein!

There are so many! I have already commented on Caddy Shack. LOVE it! I also enjoyed Galaxy Quest, Austin Powers, The Princess Bride, The Jerk (soooo funny), National Lampoon's Vacation...and even better yet is National Lampoon's CHRISTMAS Vacation (I love this film...year 'round!! Mel Brooks films...Robin Hood - Men in Tights (Oh my gosh - too funny!) and SpaceBalls (hilarious). Airplane and Ghostbusters are another couple classics! And then...of course...Monty Python and the Holy Grail - love that Black Knight scene! Then there are the oldies...yet so goodies...Bringing Up Baby, You Can't Take It With You, The Philadelphia Story, and Kiss Me Kate. I better stop...I could go on and on! :-)

does dirty rotten scoundrels count? if so thats my favourite,if not then i would have to say twins,danny devito is wicked

I'm going to have to go with Airplane! There are many funny ones, but Airplane is just hilarious. The humor is so dry and ridiculous at points, but that is partially why it's just so great. I also really like Billy Madison with Adam Sandler, he is hilarious!!
