He's a spoiled brat whose mommy owned the 'Comedy Store' or similarly named club in LA. He grew up under the wings of some of the biggest names in comedy......and learned fucking nothing.
He had a reasonably popular stint in the late '80's and very early '90's as an MTV VJ called the 'Weasel'. He acted like a retarded hippie and annoyed all who watched him that were over the age of 14.
He parlayed this character outright or at least partially into several shitty comedies. I'm ceertain he's older than 35 and I've read and even heard that he gets more pussy than a gynecologist(sp?) on speed.
