Dean and Sam in “Unfinished Business”

Dean

Whoa, whoa, whoa, whoa... hold on a minute!!

Sam

What?

Dean

C'mon, dude, that's not how it happened!

Sam

No? So you never drank a purple nurple?

Dean

Yeah maybe that, but I don't say things like "feisty little wildcat" and her name wasn't Starla.

Sam

Then what was it?

Dean

[pauses] I don't know... but she was a classy chick. She was a grad student. Anthropology and folklore. We were talking about local ghost stories.
