Genndy Tartakovski

Brian, one half of the gay couple Brian and Steve on 'The Sarah Silverman Program,' is a big fuzzy nerd. Which is okay, because that's also the personality of the man who plays him, Brian Posehn.

Posehn is a zombie-loving metalhead, a fan of cartoons and comic books, and a hilarious stand-up comedian. His new album, 'Fart & Wiener Jokes,' is out April 27th, featuring a shirtless, buffed up Posehn on the cover in a heap of comedy carnage (he says he wanted it to look like a Man O' War album).

We almost didn't get to see Brian and Steve again this year. Silverman and Comedy Central were at odds over the show's budget, until the LOGO network came in and threw in more money to make the production possible. Posehn isn't sure there will be a season four, but he's got plenty of other projects on tap (a possible spinoff for Brian and Steve, a faux reality show with party rockers Steel Panther, and a new Cartoon Network show).
