Photo Bombing

I present to you, Exhibit A.  This is not so much a picture of Danile Craig and Rachel Weisz but rather of the bottom behind them.  Does she get any credit?  Nooooo.  I'm sure you've heard of photo bombing.  Well this takes it to a new level.  Has your behind ever made it into a picture?  Mine made it into a picture with Troy Aikman (yes, wouldn't you know it was a sports event. haha)  I am going to try and find it.  It's classic.
