Sam: Maybe we should split up, ask around, see if anyone's seen him.
Dean: Yeah. Asian kid, yay high, at a university. That should be easy.
Crowley: Dean. Looking... well, let's just say Purgatory didn't do you any favors. Where's your angel?
Dean: Ask your mother.
Crowley: There's that grade-school zip. Missed it. I really did.
Crowley: Chin up, gentleman. I'm a professional.
Dean: This ain't over by a long shot, Crowley.
Crowley: Really, Dean, who writes your stuff? A marshmallow?
Sam: Kevin? How you holding up?
Kevin Tran: Awesome. The King of Hell just snapped my girlfriend's neck. How 'bout you?
Dean: So you dropped your peanut butter in her chocolate.
Reese's Peanut Butter cups featured a series of ads where two people, one holding peanut butter and one holding chocolate, would bump into each other and mix their food. The result was Reese's Peanut Butter Cups, "two great tastes that taste great together."
Dean: Thirty-one flavors of bottom-dwelling nasties.
Baskin-Robbins uses the slogan "31 flavors," although they often have more at individual stores.
