Dr. Lawrence Kutner

Dr. Lawrence Kutner (Kal Penn) was #6 on his application for the fellowship. He was initially fired, but he turned his number card upside down, turning it into a #9 and proposed the idea of stress testing a patient's liver by alcohol intoxication. This amused House and allowed Kutner to stay.

Out of all the new fellows, Kutner takes the most risks and partakes willingly in House's antics, including grave-digging and breaking into patient's houses. He is also the most enthusiastic.

Dr. Kutner is jokingly titled by House the "Chief Defibrillist", because of his quick use of the defibrillator to save two patients. In both situations Kutner either set the patient on fire or shocked himself. His recklessness because of this is a reason why Cuddy disapproves of him; so she had arranged with Cole, another "contestant" to force House to fire Kutner. However, this backfired on Cole and Kutner was successfully hired by House to be a member of the new team.
