Ken Jeong, aka Dr. Ken, is an actual Doctor who got his medical degree at UNC Chapel Hill in 1995. However, now it looks like Dr. Ken has done much better in show business after his many roles in comedies including Knocked Up, Pineapple Express, Role Models, and his breakout role in The Hangover.
Now, it seems like poor Ken is stuck in his contract and repeatedly guest starring on Community as Senor Chang.
Chang: I'm out. I chang-ed my mind.
