When it comes to The Hangover, simply type "The Simpsons The Hangover" into Google and you'll get a ton of "Simpsons did it!" results. Yes, The Simpsons beat the makers of the movie trilogy to the punch by a solid decade. While the plots aren't all that similar, a lot of the "scenery" along the way is. Mike Tyson? Sure, in the form of Drederick Tatum. A drunken night? You betcha. Waking up lacking a memory or two? We think so... A quickie Vegas wedding to a girl of questionable repute? Absolutely. The tiger? But of course! "Viva Ned Flanders" debuted in 1999. The Hangover came out in 2009. Imitation? Coincidence? Does it matter?
