If you're looking to find some of the funniest movies of all time, then these five comedies are definitely bound to make you give in and buckle down into laughter. Screwball comedies, graphic animated comedies, college comedies, and more—they're all here. What could be more hilarious than be stuck in a seemingly never-ending time loop with Bill Murray? Or helping the bad boys of "Animal House" devise their latest prank to prevent them from getting kicked off of campus? 

  1. "What's Up, Doc?." This is by far the funniest movie of all time, hands down. The screwball comedy genre has gone out the window since the days of "What's Up, Doc?" but hopefully they'll make a comeback again. This comedy shows just what potential the genre has if it is done correctly. 

  2. "Groundhog Day." Bill Murray and Andie MacDowell star in one of the funniest movies of all time. "Groundhog Day" sees Bill Murray as a weather man and reporter who ends up stuck in a time loop that forces him to relive the same day over and over again -- Groundhog Day! Murray and Director Harold Ramis simply are pure comedic genius together in this film.

  3. "National Lampoon's Animal House." This classic comedy film packs an all-star cast that ranges from Tim Matheson, John Belushi, Kevin Bacon, to Karen Allen to name a few. Being among one of the most memorable funniest movies of all time, "Animal House" follows a college frat crew who rebel against the campus superiors and their rival fra brothers as they try to get them kicked out of college.

  4. "South Park: Bigger, Longer, and Uncut." This is the popular yet graphic animated comedy show's big leap to the big screen. "South Park: Bigger, Longer, and Uncut" is all that it says it is in the title. This time, the boys on South Park find themselves up against the Anti-Christ, an impeding war between the U.S. and Canada, and censorship itself.

  5. "The Naked Gun: From The Files of Police Squad." After a brief run as a television show, Leslie Nielson reprised his role as Detective Frank Drebben of Police Squad on the big screen. "The Naked Gun" is a comedy classic from top to bottom, it is without a doubt one of the funniest movies of all time.
