Description from Netflix: When three friends (Ed Helms, Zach Galifianakis and Bradley Cooper) finally come to after a raucous night of bachelor-party revelry, they find a baby in the closet and a tiger in the bathroom. But they can't seem to locate their best friend, Doug (Justin Bartha) -- who's supposed to be tying the knot. Launching a frantic search for Doug, the trio perseveres through a nasty hangover to try to make it to the church on time.
I didn't think this was as good as everyone else did. It's not my sense of humor. They try to make this based in reality, but stuff that happens is completely unrealistic. Which is why (and I can't believe I am saying this) I think "Dude, Where's My Car?" did this storyline better.
