House Season 6 Episode 17

House: No cards, no flowers, not even a phone call. Let me guess, lighthouse keeper?
Nash: I was a classics professor at Princeton for 26 years. Mostly research.
House: So, your closest colleagues died 2,000 years ago, that must be it. Not that you have no friends because, say, you're a miserable bastard.

Nash: You're Dr. House, aren't you?
House: Oh, God, don't tell me we used to date.

Thirteen: Truth.
Dr. Wilson: All right. Have you ever had a threesome?
Thirteen: No.
Dr. Wilson: You haven't?
Thirteen: Wait, just--just because I'm bisexual?
Dr. Wilson: Well, yeah.
Thirteen: Do you understand what bisexual mean? It doesn't mean you have sex with two people at once.

(reading House's confidential files)
Taub: Look at this one. Patient lost four liters of blood from a botched... penisectomy.
Dr. Foreman: On a patient named Lisa Cuddy? Damn it. They're all named Lisa Cuddy.
Taub: He's not even here and he's screwing with us.

(Taub slugs Foreman in the face)
Dr. Foreman: I wasn't ready.
Taub: What were you gonna do? Flex your goatee muscles?

House: We're better off alone. We suffer alone, we die alone. Doesn't matter if you're a model husband or father of the year. Tomorrow will be the same for you.
Nash: But yesterday would have been different.

Dr. Wilson: That woman, the woman I'm not involved with, her name is Sam Carr. But in 1990 and 1991, it was Sam Wilson.
Thirteen: Your ex-wife?
Dr. Wilson: No, my mother. Yes, my ex-wife.
