Kelso: This chapter just helped me figure out the answer to you and Donna's problem, vis-a-vis your crappy score.
Eric: "Vis-a-vis"?
Kelso: It's a PBS word, Eric. Stay with me here. Yeah, I liken your situation to that of Pavlov's dog. You see, Pavlov was this science guy and every time his dog would ring a bell, Pavlov would eat.
Eric: Are you sure it was the dog who rang the bell?
Kelso: Yeah. I mean, who else would it be?
Eric: Pavlov?
Kelso: Well, that wouldn't be a trick, Eric. I mean, what man can't ring a bell? Anyway, every time that dog would ring that bell, old Pavlov would eat, and then he would drool.

Kitty: You know, maybe Eric's bad score is a blessing. It'll be a good story when he's a senator.
Red: "Senator"? The word you're looking for is "janitor."
Kitty: Okay, see? That's why Eric did so poorly on that test. It's because you're too hard on him.
Red: I have to be hard on him, 'cause you always baby him.
Kitty: Because you're so hard on him.
Red: You babied him before I was hard on him.
Kitty: Because you're so hard on him.
Red: You babied him before I was hard on him.
Kitty: You were hard on him when he was a baby.

Eric: Ground me.
Red: What?
Eric: I am not strong enough. If I'm gonna shake this Donna thing, I am gonna need some serious discipline. Please ground me.
Red: You got it, pal. You're grounded.
Eric: One more thing. Donna's in the kitchen. I need you to get rid of her for me.
Red: Do I have to be nice about it?
Eric: No.
Red: This is the happiest day of my life.
