A new trailer for 'Hangover 3' has hit the web. It will be the final movie in the trilogy and promises to send the boys out in hilarious "Wolf Pack" style.

Bradley Cooper, Ed Helms and Zack Galifianakis are back (and so is Justin Bartha but who really cares) for one last mission in the name of insanity. The official IMDB synopsis explains that in 'Hangover 3' "there's no wedding. No bachelor party. What could go wrong, right? But when the Wolfpack hits the road, all bets are off."

In 'Hangover 3' our favorite bachelor party bozos Phil, Alan and Stu return to Las Vegas one last time. This can't be good. Especially because John Goodman shoots a dude. It's probably a better end than what befell that poor giraffe.

'Hangover 3' hits theaters on Memorial Day 2013.
