It seems that a well over half of Arab Muslim males are named Ahmend or Mohammed. If you went to Baghdad and yelled, "Hey, Mohammed!" half the men would say "What?". If you answered, "Where's Ahmed!", the other half would turn around and say, "I'm right here."
Could get pretty confusing when assigning terror tasks. "Mohammed, you plant the bomb and Mohammed, you detonate it. No, not you, Mohammed. I meant Mohammed. No the OTHER Mohammed."
Mohammed is common, yes. But surname Atta?
that sounds like a good Mel Brooks movie. =) and the title of the movie is "Holy Shiite"
