Supernatural, Season 5

Dean:
I've got some questions for you.

Dr. Cartwright:
What a coincidence; I've got some for you too.

Dean:
Well then, Quid pro quo, Clarice. (hisses.)

Dr. Cartwright:
Okay Hannibal, I'll go first. How many hours a night do you sleep?

Dean:
Three or four, every couple of nights. What can you tell me about the recent suicides in here?

Dr. Cartwright:
They were tragic.

Dean:
But you haven't noticed anything strange? Like, uh, I don't know, black smoke, sulfur...

Dr. Cartwright:
No, why, what's that supposed to mean?

Dean:
Demon signs. I hunt demons, monsters, that kind of thing.

Dr. Cartwright:
How many drinks do you have a week?

Dean:
Well, I gotta sleep some time, so, uh, with seven days, times...it's somewhere in the mid-fifties.
