A stand-up comedian who built a career on a dry, self-deprecating, deliberately awkward stage persona, finishing as runner-up on the eighth season of America's Got Talent after becoming a favorite of judges Howie Mandel and Howard Stern. He was later named Heidi Klum's all-time favorite act on the show's tenth-anniversary special, and at nineteen became the youngest comic ever to appear on The Late Late Show with Craig Ferguson.
