Michael Bloomberg -- the current mayor of New York City -- appeared as a guest on 'The Daily Show' (weeknights, 11PM ET on Comedy Central). While he was on the show, Jon Stewart tried to use a little deceit, in order to get a special privilege.

Jon asked the mayor for his autograph on a glossy photo. "Just right on the line there; that'd be great ... that's terrific," he said. Next, Stewart whipped away the photo ... to reveal that the mayor had just signed a "All Access Five Borough" free parking pass that was lying underneath. Nice! Well-played, Mr. Stewart!

But then, Mayor Bloomberg revealed that he had signed Jon's name on the form, not his own. Stewart yelled and shook his fist at the sky: "BLOOMBERG!" Oh well. We suppose Mr. Bloomberg is just more crafty like that. After all, you can't become mayor of NYC, and the 8th richest man in America without having some street-smarts.
