But they can't seem to locate their best friend, Doug – 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.

Trivia, insights & behind the scenes
The tiger was real—Ken Jeong's naked jump from the trunk was filmed in one take because the actor was genuinely terrified.
