The sign-in sheet to the morgue held up by Foreman was creased when he showed it to Chase. When he later burns it, the crease is gone.
Dr. Chase: You actually fired your girlfriend?
Dr. Foreman: Yes. You two are both competent, and I know I can work with you.
Dr. Chase: You really do know how to woo.
House: (seeing his original team) Oh, my God. It's three years ago. Does that mean I'm still crazy?
Dr. Cuddy: You're in charge, he sits in on all the differentials. Until you get your license back, this is all unofficial. No procedures, no patient contact.
House: Think I can probably deal with that last one.
Dr. Wilson: How was your first day of school?
House: I didn't pee once in the sandbox.
Dr. Wilson: How was it with Cuddy?
House: What did you think I was talking about?
Dr. Wilson: It's just a wild coincidence that he thought you were a rude jerk.
House: Come on. Give me the benefit of the doubt. You said he's a jerk. I barely talked.
Dr. Wilson: You talked!
Injoke: House's comment about Thirteen not being the hottest woman in the world, refers to Olivia Wilde (Thirteen) being ranked #01 on Maxim magazine's 2009 Hot 100.
