She acknowledges her Internet fans, and gives them credit for getting her the gig. But she also expertly wields the mild shock factor her recent appearances have capitalized upon: An 88 year old woman! Talking about sex! Or trash-talking on the football field, whatever. And it works well, here as elsewhere, even if we'd all like to institute a permanent ban on the use of the word "cougar."
Still, here's hoping that Saturday Night Live realizes you can't fill an entire show just with a single type of punchline. Although it hasn't stopped them before.
