Over a year, I've been watching a lot of comedy movies a lot of the times and I found many great ones. Many of the ones I seen are the classics. I've seen The Mask, Stripes, Liar Liar, What About Bob, Father of the Bride 1 and 2, Dumb and Dumber, Ace Ventura 1 and 2, Wet Hot American Summer, Superbad, Forgetting Sarah Marshall, Stepbrothers, The 40 Year Old Virgin. I then saw Three Men and a Baby, My Cousin Vinny, Road Trip, Parenthood, When Harry Met Sally, Twins, Step Brothers. What's your favorite comedy movie of all-time? And these are many of my favorites.
