Lots of good ones already mentioned. I love Mel Brooks movies and just about anything with Leslie Nielsen for constant humor. I have to add in Dumb and Dumber as one of my favorites. There are scenes that still get me rolling after seeing it over 100 times.

So many good ones have been mentioned, but if you haven't seen "A Million Ways to Die in the West" you should put it on your list. One of those movies I end up quoting with a chuckle all the time. "People die at the fair."

1. Blazing Saddles
2. Blazing Saddles

1. Yes definitely blazing saddles
2. Young Frankenstein with Gene Wilder. The guy that plays Igor in that movie is just hilarious. Just the way he looks in that movie is a hoot.

I know this is against the rules but ( The Hangover ) has got to be one of the funniest movies ever made. When that naked dude jumps out of the trunk with the tire iron and says " you want f*** on me! " I had to stop the movie and laugh for 20 minutes before I could start it again.
