At 4’4," Brad Williams hasn't let his height become an obstacle. The comic was born with a disability that's become the basis for all his jokes. Carlos Mencia reportedly discovered him one night and made him his opening act. Williams has also made countless appearances on shows like Jimmy Kimmel Live, Jackass and The Tonight Show with Jay Leno. His high energy combined with his raw skits about relationships and sex translates well to the stage. Williams performs tonight at 7:30 at the Improv Comedy Club. Tickets are $17 to $20. He's at the Improv through Saturday. (Lisa Hammond)
