Bart: "I tell you, I feel really good here. And I feel generous. Danny, what do you want?"
Danny: "A piano."
Bart: "Excuse me?"
Danny: "I want a piano."
Bart: "A piano? Oh yeah. How about a lobster dinner?"
Danny: "I want a piano."
Bart: "How about a woman? You've never had a woman."
Danny: "I want a piano."
Bart: "Danny, you're starting to piss me off."
Danny: "I want a piano."
Bart: "That's what I love about you, Danny. One thought at a time."

Wyeth: "That thing with the collar... how did you do that?"
Bart: "Like my saint of a mom used to say: 'Get 'em young, and the possibilities are endless'."
Wyeth: "I thought it was the Jesuits who said that."
Bart: "Probably got it from my mom."

"You're a dog! You're my dog!"

Infirmier: "So you essentially turned a man into a dog."
Bart: "Like my saint of a mom used to say: 'Get'em young enough and the possibilities are endless'."
Infirmier: "Let me see if I've got this straight. Now I don't pay you, you take his collar off.
Bart: Correctomundo."
Infirmier: "You take his collar off, he beats us all to death."
Bart: "Now who's the bright penny!"
Infirmier: "So it seems it's in my best interest to keep that collar on, then."

"Look who's come home to his lovin' uncle Bart!"

Bart: "What's wrong with you?"
Danny: "I don't wanna hurt people anymore."
Bart: "Excuse me. Danny, that's what you do. You hurt people."
Danny: "Not anymore."

"If you can't do what I've trained you to do, what fucking use are you? No fucking use is the answer. No fucking use at all."

"It's all going on the bill Danny-boy. You hear me? It's going on the bill."
