House, Season 7

[House checks the patient, Danny's pulse]

Danny:
Who are you?

House:
Shhh!

Danny:
What are you doing?

House:
Test.

Danny:
Who are you?

House:
The important question is, who are you? Danny Jennings is dead, which means that Danny Jennings has no pulse. You, on the other hand… do. Ergo, you are not Danny Jennings. [leans his cane against the bed] Or I did the test wrong. So why don't you cut the crap and tell me your real name.

Danny:
No.

House:
Hiding your identity… Well, either you're a criminal or a superhero.

Danny:
I'm not a criminal.

House:
Awesome. What color is my underwear?
