Supernatural 4x16: On the Head of a Pin

Very clever title, referencing the age-old philosophical question "How many angels can dance on the head of a pin?" I'd love to go into all the reasons why this title was so cool for this particular episode on so many different levels, but that would take a while. :P

( So let's talk spoilery talk for the episode instead (beware of season 5 spoilers, too) )

Quotes -

Dean: I'm just, I'm just gettin' tired.
Sam: Well, get angry.

Dean: Ah, home crappy home.

Uriel: You are needed.
Dean: Needed? We just got back from needed!

Dean: Well, get some donuts while you're out.
Uriel: *laughs* Oh, this one just won't quit, will he? I think I'm starting to like you, boy. *disappears*
Dean: You guys don't walk enough. You're gonna get flabby.

Castiel: Uriel's the funniest angel in the garrison. Ask anyone.
