Comedian Samuel J. Comroe is probably best known as a contestant on season 13 of America’s Got Talent, where he placed fourth. At the age of 6, he was diagnosed with Tourette’s Syndrome. “You don’t know what it’s like when a haircut becomes a life-or-death situation,” he tells an audience. His condition is exhibited by an occasional twitch. “Don’t hang out with children,” he warns. “They’re assholes. My 6-year-old nephew asked me, ‘Why does it look like a ghost is punching you in the face?’ It’s true. I started to cry, but even that was embarrassing, because my tears run sideways.” His set isn’t all, or even mostly, about his disability, though. After all, his comedy special is calledI’ve Got 99 Problems but a Twitch Ain’t One.
