Christine

Will Darnell: "'Kiddo, you sold him that piece of shit, you oughta be fuckin' ashamed of yourself."
Dennis Guilder: "I didn't sell it to him. I tried to talk him out of it."
Will Darnell: "You shoulda' tried harder."

"She smiled at me. I want to have deep, meaningful sex with her."

Rudolph Junkins: "The kid was cut in half Arnie, they had to scrape his legs up with a shovel."
Arnie Cunningham: "Well, isn't that what you're supposed to do with shit? Scrape it up with a little shovel?"
Rudolph Junkins: "Don't get smart with me, son. Your girlfriend is a hell of a lot more convincing than you are."
Arnie Cunningham: "She's not my girlfriend. And since when is it against the law to fix up your own car when somebody else busts it up, huh?"
Rudolph Junkins: "...since never."
Arnie Cunningham: "Then you get off my back."
Rudolph Junkins: "Okay."

"Some shithead's following me!"

Arnie Cunningham: "Let me tell you a little something about love, Dennis. It has a voracious appetite. It eats everything. Friendship. Family. It kills me how much it eats. But I'll tell you something else. You feed it right, and it can be a beautiful thing, and that's what we have. You know, when someone believes in you, man, you can do anything, any fucking thing in the entire universe. And when you believe right back in that someone, then watch out world, because nobody can stop you then, nobody! Ever!"
Dennis Guilder: "You feel this way about Leigh?"
Arnie Cunningham: "What? Fuck no! I'm talkin' about Christine, man! No shitter ever came between me and Christine..."

George LeBay: "What the hell do you want?"
Dennis Guilder: "I know about your brother. I know he died choking on exhaust fumes."
George LeBay: "You don't know shit, kid. My brother died because he wanted to. He ran a rubber hose from the exhaust pipe."
Dennis Guilder: "Arnie would have never bought that car if he'd known somebody died in it."
George LeBay: "Either you're dumber than you look, or you don't know your friend very well. He had the same look in his eye that my brother always had. Probably the only thing my brother ever loved in his whole rotten life was that car. No shitter ever came between him and Christine, if they did... watch out! He had a five-year-old daughter choke to death in her... he wouldn't get rid of her. He just rode around with the radio blaring, not a care in the world except for Christine. Only time I ever interfered with it was when Rita killed herself."
Dennis Guilder: "Who's Rita?"
George LeBay: "His wife! He didn't care a rat's ass about her! She died the same way he did... then I made him get rid of it... for decency, ya know? Of course, the car came back three weeks later."
Dennis Guilder: "What do you mean 'came back'?"

"Has it ever occurred to you that part of being a parent is tryin' to kill your kids?"

"Ya know Pepper, ya can't polish a turd."
