7 memorable 'SNL' appearances by politicians and candidates

Mayor Rudy Giuliani, who ran for president in 2008, showed up on "SNL" many times, including as host in 1997. But his most poignant moment came in 2001 when he appeared with members of the FDNY, other first responders and SNL creator Lorne Michaels to welcome "SNL" back following the terror attacks of September 11.

"Can we be funny?" Michaels asked. "Why start now?" Giuliani responded to huge applause.
