Former Illinois Gov. Rod Blagojevich made a special public appearance over the weekend -- at the Second City production about himself, "Rod Blagojevich, Superstar":

"What they say to you before you go out on stage I thought is very interesting and that is 'we got your back,'" Blagojevich told the audience. "I've been in politics and that's not anything anybody said to me."

This sort of thing does have a precedent. Former Australian Prime Minister Paul Keating would often attend performances of a comedic opera about himself, which was a tribute both to his policies and his monumental ego and vanity -- and he'd even get up and dance during the curtain call.
