• The Hangover
• The Big Lebowski
• O Brother Where Art Thou
• Raising Arizona
• Burn After Reading
• Fear And Loathing In Las Vegas
• National Lampoon's Christmas Vacation
• Super Troopers
• The Princess Bride
• Fargo
  • If you don't laugh while watching Fargo, you aren't paying attention to anything but the gore. I had to watch this movie a few times before I noticed the humor.
• The Women

Pretty much any of the movies that are on my favorites list make me laugh, but this list could get really long, really quickly.
