The Cunningham family live through the 1950s with help and guidance from the lovable and almost superhuman greaser, Fonzie.

The Fonz: Heyyy!
The Fonz: You're dreaming about a girl you've never met?
Richie Cunningham: Come on, Fonz, haven't you ever dreamed?
The Fonz: Hey I'm not the dreamer! I'm the dreamee!
Charles 'Chachi' Arcola: Wa! Wa! Wa!
Richie Cunningham: I found my thrill on Blueberry Hill.
Richie Cunningham: So how did you do on that social studies test?
Potsie Weber: I missed that question on Alaska. I hear they want to make it a state now.
Richie Cunningham: That'll never happen.
The Fonz: Arnold, go and cook up a couple of burgers for us.
Matsuo 'Arnold' Takahashi: But I just cleaned the grill!
The Fonz: Well, good! Then maybe they'll taste better!
The Fonz: [Marion has just told off the Fonz and stormed out of the room] I'm gonna hit her.
Howard Cunningham: No, you're not gonna hit my wife.
The Fonz: Then I'll hit you!
Howard Cunningham: You're not gonna hit my son.
The Fonz: Then I'll hit you!
Richie Cunningham: You're not gonna hit my father either.
The Fonz: Well I gotta hit somebody. You know where Potsie is?
Ralph Malph: You're such a Potsie!
[repeated line]
Richie Cunningham: Sit on it!
Marion Cunningham: Richie just hasn't got the appetite that Chuck has.
Howard Cunningham: Marion, Argentina hasn't got the appetite that Chuck has.
Ralph Malph: [Richie is worried that he's going crazy] Come on, Richie! You're no crazier than the rest of us! Look at Potsie. You think he's normal? And Fonzie... super-cool Fonzie. Fonzie with his "Ayyy!" I mean, that's pretty... that's really sicko when you come right down to it.
Richie Cunningham: I wouldn't let him hear you say that.
Ralph Malph: You tell him I said that, and I'll deny it! Every word!
Richie Cunningham: OK, Ralph - take it easy.
Ralph Malph: Now you take me - nice, normal Ralphie Malphie. I got no quirks. But I know what they're saying about me. They're saying my hair's too neat, I'm too cute, and girls crave my bod.
Richie Cunningham: They're not saying that, Ralph.
Ralph Malph: Yes they are. They're also saying that I look like a movie star because my teeth are too even.
The Fonz: You ain't nobody until you do what you want!
Richie Cunningham: A shark? That is the *stupidest* thing I have ever heard!
Fonzie: Stupid, yes. Also dumb. But it is something I've gotta do.
Richie Cunningham: Fonz, you're not jumping over garbage cans on a bike. You're jumping over a shark. On nothing! On a couple of little skis! One little slip and chomp! Chomp! Chomp!
Fonzie: Thanks a lot for your support. Look, I was challenged. I gotta jump.
Potsie Weber: Rich! Rich!
Ralph Malph: Come quick!
Richie Cunningham: What? Is there something wrong?
Potsie Weber: It's a shark!
Ralph Malph: The Fonz...
Richie Cunningham: Fonz got eaten by a shark?
Potsie Weber: He did? Who said that?
Ralph Malph: Not me! What're you talking about?
Richie Cunningham: Well, you just said "The shark..."!
Ralph Malph: Nooo! Listen! The Fonz is gonna jump *over* a shark!
Howard Cunningham: Why can't you be a normal boy and swallow goldfish?
Ralph Malph: I've still got it!
[watching a Chicago Bears football game in 1956]
Ralph Malph: That Bears quarterback is no good. He's washed up. He's 30.
Richie Cunningham: That's ridiculous. George Blanda still has a few more good years left.
[Fonzie and Pinky have had a fight and are sitting at the dinner table]
Richie Cunningham: Dad, uh, can you come upstairs with me for a minute?
Howard Cunningham: I haven't finished my dessert yet.
Richie Cunningham: Well, you can finish it upstairs, Dad.
Howard Cunningham: What are you doing?
Richie Cunningham: Well, we have to talk.
Howard Cunningham: Talk about what?
Richie Cunningham: I... I don't know... the birds and bees.
Howard Cunningham: Oh, Richard, we already had that talk.
Richie Cunningham: [refers to the table] Yeah, and you didn't learn much.
Jenny Piccalo: I wouldn't miss this for a weekend with the Green Bay Packers as their towel girl!
[Fonzie's feet are sore from dancing and needs to be held up]
Fonzie: Aaaay, I'm up and moving!
Richie Cunningham: You're in La-La land, Fonz.
Fonzie: Let me tell ya, it's a lot of fun in La-La land!
The Fonz: [Richie tries to get Fonz to get rid of a very tall, very big lumberjack] You picked a fight with a red and black tree?
The Fonz: [to his class]
The Fonz: Don't you understand, your brain is clay and I gotta *squeeze* it!
[class is startled]
The Fonz: [then calmly] Let me put that another way...
Count Mallachi: Release the doves!
