Sarah Silverman Returns ... And Has A Lot To say

Sarah Silverman stopped by to promote the paperback release of her book, "The Bedwetter" and Howard commended her work on a recent "Saturday Night Live" retrospective. Sarah said her appearance on the special surprised her.

"I couldn't believe I was on that," she told Howard. "I never got a sketch that I wrote myself on the air ... but recently I read them all. I went back. And they were terrible."

Sarah added that she was also surprised when she'd landed the "SNL" gig in the first place, as she was only 21 years old at the time and a relatively inexperienced comedian. "I didn't even know who I was comedically ... I was a good stand-up but I think they were looking for girls," she said.

Asked about a rumor that she'd once stabbed Al Franken in the "SNL" writers' room, Sarah nodded, saying she'd been admiring Al's "huge Jew-fro" and playing with a pencil. "It was a mistake ... I really just meant to put it through his hair," she explained.

But her aim was off and she wound up stabbing him in the temple, laughing as he screamed in pain. "I must've looked like a crazy person who'd just turned and stabbed someone in the temple with a pencil and laughed. I mean, there's probably lead in his temple still," she said.
