Wasn't Scott Bakula in the audience? Or was that a different "roost" where I saw him?
He was there for Bob Saget's roast.
As for Lisa Lampinelli, I can't stand her at all. I like that a lot of Shatner's friends were roasters or in the audience, but she adds nothing but cheap "humor." For all of Shatner's camp, he's in on the joke, is more nuanced and smarter than he lets on, and he doesn't talk down to you the way Lampinelli does.
