“What did the suicide bomber teacher say to his students?”/“I’m only going to show this once.”

Teachers often say, “Pay attention! I’m only going to do this once!” But what if the teacher is instructing suicide bombers?
 
A joke was posted on the newsgroup soc.culture.israel on April 4, 2002:
 
Q: What did the suicide bomber instructor say while demonstrating how to perform their trade?
A: “Now watch closely, because I’m only going to do this once!”

I am reminded of a cartoon someone sent me a few years back. I showed three men in Arab garb standing near a sign which said “Suicide Bomber School.”
 
One man, wearing a suicide vest, was saying, “Pay attention, I am only going to do this once.”
