Jeff Dunham

Fans of Walter the old man, José Jalapeno, Peanut the Woozel and Achmed the Dead Terrorist may not realize this, but the actual mastermind behind them all is their on-stage straight man, ventriloquist Jeff Dunham. But we don't think Dunham minds sharing the spotlight with his alter egos because they've helped him become one of the biggest draws in comedy, which is evident by the sheer number of comedy specials he’s appeared in, and the size of the venues he's selling out. You can now read all about Jeff's (and all of his personalities') life story in the new book All By My Selves. You can also see him and all his pals on the new Comedy Central special, "Minding The Monsters" which airs on Sunday October 7th at 9PM. Follow Jeff on twitter.

Costaki Economopoulos

Costaki Economopoulos is a comedian, true, but he's also a football fan. Those two factors alone make him the perfect candidate to give us a comedic look back at the NFL each week with his new feature that's also been picked up by The Huffington Post and Bleacher Report. With his Greek heritage, it's not surprising that he's been described as a “joke philosopher,” and we're sure he's not the only one saying that. Costaki is also a talented joke writer who's punchlines have been heard on "The Tonight Show," Showtime, BET, and MTV. Follow Costaki on facebook and twitter.

Demetri Martin

Sly, thoughtful and deadpan stand-up comedian Demetri Martin did something with sketch comedy that Comedy Central had never done before, turned it into a forum for learning on his show "Important Things with Demetri Martin." Along with being a great teacher, Martin is one of the most popular stand-up comedians in the country. He's been a contributor for both "The Daily Show" and with Conan O’Brien. He’s also appeared on the show "Flight of the Conchords" and in the films The Rocker and Taking Woodstock. Follow Demetri on Twitter
