Comedian Stephen Colbert is deaf in one ear. A surgery when he was young left him without an ear drum in his right ear. He says, "I always wanted to be a marine biologist but then I had this ear problem. I have no ear drum. So I had this operation at the Medical University when I was a kid. Now I can't get my head wet. I mean, I can, but I can't really scuba dive or anything like that. So that killed my marine biology hopes." During a 2006 segment on his show, Colbert "played the humor card."
