Adams says that the traveling x-ray machine won't be at the prison until Friday. However, House comes in on Thursday and Adams tells him that," the x-ray didn't show any tumors." It is never explained where they got the x-rays from.
Mendelson: Why you keep helping him out?
House: Yeah, why would I wanna make sure that my homicidal cellmate is taking the right anti-psychotics?
Frankie: You don't wanna mess with Stomper. He didn't get that name because he's a fan of Santa's reindeer.
House: You think one of Santa's reindeer was called Stomper?
Frankie: You're missing my point.
House: I'm not gonna listen to a guy who can't name the reindeer.
House: This another pet? Cause it's going to end badly. Again. Remember we talked about this. At least I talked, and you stared at me eerily. I think it was eerily. "Eerily" felt like the best-case scenario.
Nick: You don't believe me?
House: Belief implies a level of giving a crap that I am never going to achieve.
House: It's the greatest mystery there is--the theory of everything.
Dr. Adams: And completely divorced from humanity.
House: Well, me and humanity, we got together too young.

House: I'll dress 'em the same. Like in Vertigo.
Referencing Alfred Hitchcock's classic movie Vertigo (1958), starring James Stewart and Kim Novak with the acrophobic detective Scottie Ferguson (Stewart) becoming obsessed with an old friend's wife (Novak). A key plot point is that the wife resembles another woman, Judy, and that Judy dresses up as the wife. A poster of the movie features prominently in Wilson's office.
House: Jiminy didn't chirp much last night.
Referencing the talking cricket from the 1940 Disney movie Pinocchio, and including other references to the Blue Fairy and the song Wish Upon A Star, as well as the puppet himself. Pinocchio was created by Carlo Collodi in his 1883 story The Adventures of Pinocchio. Collodi's story tells of Gepetto, a woodcarver who makes a wooden puppet in lieu of a son and names it Pinocchio. Pinocchio aspires to be a real boy and runs away. The character is best known for the fact that his nose grows when he tells a lie.
