House Season 1 Episode 9

House: And that's all you are? Musician?
Giles: I got one thing, same as you.
House: Really? Well apparently you know me better than I know you.
Giles: I know that limp. I know the empty ring finger. And that obsessive nature of yours, that's a big secret.You don't risk jail and your career to save somebody who doesn't want to be saved, unless you got something. Anything. One thing. The reason normal people got wives and kids and hobbies, whatever, that's because they ain't got that one thing that--that hits a man hard and that true. I got music, you got this, the thing you think about all the time, the thing that keeps you south of normal. Yeah, makes us great, makes us the best. All we miss out on is everything else. No woman waiting at home after work with a drink and a kiss, that ain't gonna happen for us.
House: That's why God made microwaves.
Giles: Yeah. And when it's over, it's over.
House: Yeah. (House opens the door and starts to move Giles' bed out of the room)
Giles: What are you doing?
House: It's not over for me. Either you're gonna call the cops again or we're doing this. If you wanna die you can do it easily inside an MRI machine.
