Euphoria Part 1

When a police officer with a gunshot wound to the head and uncontrollable laughter is admitted, House and the team are baffled. When Foreman begins showing the same symptoms, they race to determine the cause of the illness before Foreman's condition takes the same path.

House: "There's a bullet in his head."
Cameron: "He was shot?"
House: "No ... somebody threw it at him."

Cuddy: "I can't even imagine the backwards logic you used to rationalize shooting a corpse."
House: "Well if I'd shot a live person there's a lot more paperwork."
Cuddy: "Then it won't be a problem for you to stand besides the casket at the wake and explain why a cancer patient has a bullet hole in his head."
House: "The man donated his body to science. Yes, it's a tragedy. If I hadn't shot him his body could have spent the next year letting first year med students use the carpool lane."

House: "I think that an appropriate response to watching your boss shoot a corpse is not to grin foolishly."
Foreman: "The fact that I've grown bored by your insanity is proof of nothing."

Cameron: "The chance of getting infected is next to nothing."
House: "I was never good at math, but next to nothing is greater than nothing."
