After eight years on the air at "Saturday Night Live," Sudeikis says he's calling it quits. Sudeikis used another late-night institution to make his announcement, telling David Letterman in the taping of the show on Wednesday, July 24, that he's leaving NBC's weekend program. Sudeikis had a busy election year on "Saturday Night Live," portraying both Republican Mitt Romney and Vice President Joe Biden. (AP Photo/NBC, Dana Edelson)
