“House, M.D.” — Season Four

For Dr. Gregory House (Hugh Laurie), there’s nothing like a good, tension-filled competition to pick his new team of doctors when his old trio of Chase (Jesse Spencer), Cameron (Jennifer Morrison) and Foreman (Omar Epps) leave his fold. Among the 40 newbies vying to earn the coveted spots in the fourth season of House, M.D. are Dr. Lawrence Kutner (Kal Penn, the Harold & Kumar films), Dr. Chris Taub (Peter Jacobson, Transformers) and Dr., uh, Thirteen (Olivia Wilde, The O.C.). Taking a cue from Flavor Flav, House dubs the latter with that nickname simply because he can.
