What happened: Chicago Mayor Rahm Emanuel, left, is the brother of Hollywood super agent Ari Emanuel, the hard-charging and sometimes abrasive head of the William Morris Endeavor talent agency. The character of super agent Ari Gold played by Jeremy Piven on the HBO series "Entourage" is inspired by Ari Emanuel. The apology: "On behalf of the entire Emanuel family, we apologize for Ari," the mayor said at the 2011 Cable Show, the annual gathering of the heavy-hitters and rank-and-file of the cable television industry. "You know him as an agent, we know him as a brother. We thought that we got the worse end of the deal."
