Saturday Night Live's 40th Anniversary special is already stacked with a cast of classic hosts, alumni, and legendary musicians. Today another guest appearance for the special was announced, and at first we thought it was just a Tina Fey impersonation. But it turns out the real life, gaffe-prone former vice presidential candidate Sarah Palin is going to make an appearance during the Feb. 15 special. 

No word on exactly what to expect from Palin, but if she doesn't appear alongside Fey we'll consider ourselves robbed. Not even Kanye West and Paul McCartney could put on a better performance.
