Whac-A-Mole House M.D. : Season 3 Episode 8

An 18-year-old teenager is brought to the hospital after having a heart attack. House reviews the boy's file and believes he has the diagnosis. He then turns the case into a game by sealing his opinion in an envelope and challenging Cameron, Foreman, and Chase to guess House's diagnosis on their own. Meanwhile, Tritter's actions against Wilson continue to strain the oncologist's relationship with House and destroy his ability to practice medicine.
