Years Active: 2005-Present

Kristen Wiig is, as Jimmy Kimmel noted, "the Kobe Bryant of SNL." Last season, Wiig racked up the second most airtime on the show ever. Even though some of her characters are scary (we're talking about the sisters from the Finger Lakes act on the Lawrence Welk's show), you can't deny that Wiig's willingness to fug herself up for a laugh makes her even hotter.
