A middle-eastern man drives up to a U.S. Customs border checkpoint with a bomb sitting in the back seat.
Uncle Sam leans out of the booth ask questions of the man as he tries to cross the border.
The middle-eastern man irately asks, "What is your coming to when a foreigner can't come in with a big can of explosives and fake identification and plane tickets to Europe and no explanation?? That's why I want to kill as many of you as possible."
POSTSCRIPT: Uncle Sam: "Okay, well that takes care of the explanation part."
