Dirk and Sam in “Unfinished Business”

Sam Winchester, still a bully. You, you jocks, you popular kids. You always thought you were better than everybody else. To you, I was just "Dirk the Jerk" right? Now you evil sons of bitches are going to get what's coming to you.

Sam

I'm not evil, Dirk. I'm not. And neither were you. Trust me, I've seen real evil. We were scared and miserable and we took it out on each other. Us and everybody else, that's high school. But you suffer through that, and it gets better. I'm just sorry you didn't get a chance to see that.
