'Blazing Saddles' tops the list of funniest movies of all times, as determined by the readers of Rolling Stone. What is the one movie that makes you laugh every time?

The readers of Rolling Stone placed five of my favorite funny movies of all time in the top 25 including Planes, Trains, and Automobiles starring Steve Martin and John Candy at #20,  Dumb and Dumber with Jim Carrey and Jeff Daniels at #9, Young Frankenstein starring Gene Wilder and Mel Brooks at #5, and Airplane  at #2.

Two funny movies notable missing from my list of funny movies would be Mrs. Doubtfire starring Robin Williams, and Liar Liar with Jim Carrey. Both of these movies make me laugh time and time again.

There have been so many funny movies made over the years, but how many of them make you laugh out loud EVERY time you watch them? That is the mark of a truly funny movie.
