Miss USA Eats It in Mexico

Miss USA Rachel Smith took a butt-tacular spill last night in Mexico City at the Miss Universe competition, and if you haven't seen it yet, you won't quite believe the arse-shaking thud!

What's just as amazing as the actual fall is how quickly Miss Smith gets back up and into perma-smile mode, despite the jeers and titters of the crowd.

Miss Japan won the competition, in case you were wondering.
