Secret Service Crashes Art Exhibit It's not unusual for guys in Ray-Bans to show up at an art exhibit. But these guys weren't just being cool. The Secret Service was checking out a particular work at an exhibition at Columbia College in Chicago called Axis of Evil: The Secret History of Sin. It features mock postage stamps -- one of which shows a gun pointing at the head of President Bush. A Secret Service spokesman explained they just wanted to make sure it's "nothing more than artwork, with a political statement."
