Some celebrities aren't made, they're born. Vince Offer (yes that is his actual name) became a viral sensation with his over-the-top commercials. He started his career as a comedian and a writer, but he started acting as a way to pay his rent. Acting quickly became more commercial gigs, and Vince found his footing by doing infomercials. It was better since they were longer than standard commercials.
