It remains to be seen whether Tina Fey will make an appearance as Gov. Sarah Palin during "Saturday Night Live's" season premiere tonight, but the show did sign another high-profile guest.
Sen. Barack Obama will make a cameo during the program, according to NBC. It will be Obama's second "SNL" appearance. In November, he played himself in a sketch about a Halloween party hosted by Sen. Hillary Rodham Clinton.
