Pittsburgh Mayor Luke Ravenstahl really loves his city's NFL football team, the new Super Bowl champion Steelers. He took that love to new extremes in January, when he temporarily changed his last name to "Steelerstahl" before the Steelers' AFC Championship Game against the Baltimore Ravens, according to the Associated Press. Mayor Rav … uh, Steelerstahl got the idea from callers to a local radio station's morning show. "As soon as I heard it, I thought it was a great idea," the mayor said. Ravenstahl has returned to his old name after declining to complete the legal name-change process that he began.
