I recently stumbled across this very interesting joke by journalist Greg Palast. You should read the entire original article, but let me share this quote with you:
So, Osama Walks into This Bar, See? and Bush says, “Whad’l’ya have, pardner?” and Osama says, “Well, George, what are you serving today?” and Bush says, “Fear,” and Osama shouts, “Fear for everybody!” and George pours it on for the crowd. Then the presidential bartender says, “Hey, who’s buying?” and Osama points a thumb at the crowd sucking down their brew. “They are,” he says. And the two of them share a quiet laugh.
