Dr. Wilson: You're just mad that he's closer to a Nobel Prize than you are.
House: And yet I've nailed more Swedish babes. Crazy, crazy world.

House: Judging by the scratches on your hands, I'm guessing...new cat.
Mandy: It was my mother's. She's dead.
House: You keep a dead cat?
Title: TB or Not TB
The episode title is an obvious pun of Shakespeare's famous quote from Hamlet, "To be, or not to be".
