Ken Jeong

The Community star is a comedian these days, but his first career was in medicine in California, where he was a licensed physician. His medical training helped him at a gig in Phoenix in May when a woman began having a seizure in the audience, but let's hope he doesn't have to use it again in Atlantic City.
