Sam came to the clinic because his left hand was numb. He was seen by Robert Chase who started to perform a physical examination. Suddenly, Gregory House bursts in to do a differential diagnosis with Chase. Chase tries to brush him off but agrees to provide some ideas. House finally goes to leave, but when he finds out Sam's hand is numb, he points out that Sam's watch band is on too tight and is obviously cutting off blood circulation. Sam removes his watch and instantly starts to feel better.
