Some guys just can't handle Vegas.
When three friends finally come to after a raucous night of bachelor-party revelry, they find a baby in the closet and a tiger in the bathroom.

Launching a frantic search for Doug, the trio perseveres through a nasty hangover to try to make it to the church on time.

Naturally, they've lied about their destination and head straight to Vegas for a night of fun and frolicking.
