Bobby Singer: Karen?
Karen Singer: You were expecting Farrah Fawcett?
Bobby Singer: No. She always calls first.

Rufus Turner: Seriously, though, Bobby, how come...?
Bobby Singer: Dog with a bone, Rufus.
Rufus Turner: No, I really want to know, man--why no kids?
Bobby Singer: Ain't that deep. Dad was a mean drunk. I figured I'd be just like him. And, hey, look, I was right. No sense passing on the legacy.
Rufus Turner: You're too hard on yourself. You're more of a cranky drunk.

Dean: We're coming for you. And not just to hurt you--to kill you. You understand me?
Dick Roman: Come on, Dean, I can't be killed.
Dean: You're gonna wish you could, then.
Dick Roman: (laughs) That's some conviction. You'd really crush it on the motivational circuit.
Dean: You're either laughing because you're scared or you're laughing because you're stupid. I'll see you soon, Dick.

Reaper: Bobby... you've helped. You got handed a small, unremarkable life, and you did something with it. Most men like you die of liver disease, watching Barney Miller reruns. You've done enough. Believe me.
Bobby Singer: I don't care.
Reaper: Why?
Bobby Singer: Because they're my boys.

Bobby Singer: Well that's a load of crap. Who the hell were you to say?
Ed Singer: I'm your father. And you show your father respect.
Bobby Singer: The day he deserves it. You drunken bully. Punching women and kids, is that what they call fatherhood in your day?
Ed Singer: You deserved it. Believe me, you were nothing but ungrateful.
Bobby Singer: I was a kid! Kids ain't supposed to be grateful. They're supposed to eat your food and break your heart, ya selfish dick! You died and I was still so afraid I'd turn into you, I never even had kids of my own.
Ed Singer: Good. You break everything you touch.
Bobby Singer: Well, as fate would have it, I adopted two boys and they grew up great. They grew up heroes. So you can go to hell!

Dean: All right, scoot, jerkface. Show your elders some respect.
Sam: You scoot, asshat.
Dean: Did we get licorice?
Sam: No, we did not get licorice. We got good snacks. Licorice is disgusting.
Dean: I'm sorry, I didn't quite understand that, uh, Mr. "Peanut Butter and Banana Sandwich."
Sam: I stand by that sandwich. Nobody likes licorice. It's--it's made of dirt.
Dean: It is a classic movie food. It's right up there with popcorn.
Sam: Popcorn?
Dean: Yeah.
Sam: You're out of your mind.
Dean: What, it's like little chewy pieces of heaven.

Bobby Singer: Hey, what are you making like a White Rabbit all over the place for, you grubby little...

The White Rabbit is a character in Lewis Carroll's Alice's Adventures in Wonderland (1865). A giant anthropomorphic rabbit, he is inevitably late for any daet.

Bobby Singer: I’m still stuck in eternal friggin’ sunshine.
