Season 3, Episode 11
On a job in a small town, Sam faces his own Groundhog Day where Dean keeps dying in new and interesting ways.
Dean: Find anything?
Sam: No.
Dean: Do you have any idea what you're looking for?
Sam: Uh, yeah. No.
Sam: Man, I had a weird dream.
Dean: Yeah? Clowns or midgets?
Dean: Sammy, I get all tingly when you take control like that.
Dean: Did it look cool? Like in the movies?
Sam: You peed yourself.
Dean: Of course, I peed myself. Man gets hit by a car, you think he has full control of his bladder?
Sam: I knew it was going to happen, Dean. I know everything that's going to happen.
Dean: You don't know everything.
Sam: Yeah, I do.
Dean and Sam (in unison): Yeah, right. Nice guess.
Sam: It wasn't a guess.
Dean and Sam (in unison): Right, you're a mind reader. Cut it out, Sam. Sam, you think you're being funny but you're being really childish. Sam Winchester wears makeup. Sam Winchester cries his way through sex. Sam Winchester keeps a ruler by the bed and every morning when he wakes up. Ok, enough.
Trickster: Whoever said Dean was the dysfunctional one has never seen you with a sharp object in your hands. Ho-ho-holy full metal jacket!
