The Hangover (2009)
The Hangover is peak bro comedy, but it’s so ridiculous and the bits play out so well that this raunchy party film is absolutely hysterical. When three groomsmen (Bradley Cooper, Zach Galifianakis, Ed Helms) get so wasted that they lose their best friend in Las Vegas during a bachelor party gone wrong, they’re forced to uncover their foggy memories to find out where he could be in order to get to the wedding on time. Of course, it’s a shit show -- with insanity ranging from tigers, random babies, an appearance by Mike Tyson, and lots of drugs -- but there’s never a dull moment. Just lean into the “what happens in Vegas” vibe and enjoy the trip.
