Elisabeth Hasselback First Career

Ken Jeong, doctor:
Actor and comedian Ken Jeong quickly became one of the most in-demand supporting actors after cameos and memorable roles in the TV show Community and of course, The Hangover, but Jeong wasn't a struggling actor before landing some of the biggest comedies in recent years. Knocked Up was actually Jeong's first film, and before getting into the movie business, Jeong was an internal medicine doctor. He graduated from University of North Carolina Chapel Hill's medical school, completed his residency in New Orleans, but then won a stand-up comedy competition and moved to LA, where he began appearing in top shows like Curb Your Enthusiasm and The Office.

Stephen King, teacher:
Just imagine if your teacher was going home at night and writing horror novels and screenplays? It might make you turn in your homework on time, or stop passing notes, at least. Stephen King � the legendary writer behind Carrie and The Shining� taught high school English in Hampden, Maine, writing during the weekends and in the evenings.

Mike Rowe, opera singer: Mike Rowe is best known in the U.S. for hosting the Discovery Channel's show Dirty Jobs, but if you listen carefully, he's also the narrator behind lots of commercials, TV specials and documentaries. But that strong, gravely voice isn't just great for speaking. Before TV, Rowe sang with the Baltimore Opera.
