Supernatural, Season 6

Dean:
We should call Cas.

Sam:
You kidding, right?... Dean, I tried. It was the first and second and third thing I did as soon I get topside. Son of the bitch won't answer the phone!

Dean:
Well, let's give it a shot. Now I lay me down to sleep. I pray to Castiel to get his feathery ass down here.

Sam:
You're an idiot.

Dean:
Stay positive.

Sam:
Oh, I am positive.

Dean:
C'mon, Cas. Don't be a dick. We got ourselves a... plague-like situation down here. Do you...Do you copy? [Nothing happens]

Sam:
Like I said, the son of the bitch doesn't answer. [Castiel appears behind Sam, Dean sees him] He's right behind me, isn't he?

Castiel:
Hello.
