House, Season 4

Dr. House:
I saw something amazing: pure truth. She told her mother that she was dying. Stripped her of all hope.

Dr. Wilson:
[haltingly] That sounds... horrible.

Dr. House:
It was like watching some... bizarre astronomical event that you know you're never gonna see again.

Dr. Wilson:
You tell people the cold, hard truth all the time. You get off on it.

Dr. House:
Because I don't care. She cared. [thoughtful] She did it anyway. She did it because she cared.

Dr. Wilson:
[sarcastically] The angels of Christmas have finally given House a present he can appreciate.

Dr. House:
Oh, don't ruin it. Don't pin this on Christ, he's got enough nails in him.
