MTV Movie Awards Moments That Surprised Viewers

With categories like Best On-Screen Dirt Bag, Best Kiss, and Best Scared-as-S--t Performance, the MTV Movie Awards have a tendency to be slightly less stuffy than their more serious awards show counterparts.

Over the years, the awards shows have produced some major surprise moments, from a naked Rainn Wilson, to an unexpected lip-lock from "Twilight" stars Robert Pattinson and Taylor Lautner.

Airing on Sunday evening, this year's MTV Movie Awards will be hosted by Rebel Wilson. With Wilson's over-the-top humor and a confirmed appearance by Kim Kardashian, the 2013 awards are sure to produce some scandalous scenes as well.
