- Arthur 'Fonzie' Fonzarelli: Some guys are good lovers, and some guys are good fighters. I happen to be both.
- Ralph Malph: Wait a minute, Arnold. The paper said Mitsuma Tokahashi is giving the class.
- Arnold: I am Mitsuma Tokahashi. Is this the face of a Arnold?
- Ralph Malph: Why'd you change your name?
- Arnold: What change? I buy a restaurant, had a big sign, "Arnold." Signs very expensive. You know how many letters in "Tokahashi"?
- Marion Cunningham: Good morning, Richard. Would you like cornflakes for breakfast, dear?
- Richie Cunningham: [through clenched teeth] I never want cornflakes again. Oatmeal!
- Marion Cunningham: Oh. Well, I thought you liked cornflakes.
- Richie Cunningham: [slaps the table] Oatmeal!
- Marion Cunningham: I'll make oatmeal!
- Howard Cunningham: What kind of a way is that to talk to your mother?
- Richie Cunningham: Oh, I'm sorry, Mom. Cornflakes are OK. You see, I was just trying out some advice that Fonzie gave me. He said if you sound tough, people listen. And it works!
- Richie Cunningham: Let's face it -- you're a good fighter.
- Arthur 'Fonzie' Fonzarelli: Hey, I'm the best. But in the entire time you've known me, have you ever seen me in a fight?
- Richie Cunningham: Well, no, but that's because the other guy always backs down first.
- Arthur 'Fonzie' Fonzarelli: I rest my case.
- Arthur 'Fonzie' Fonzarelli: Hey, lemme tell you somethin'. Everybody gets scared. If you're gonna survive in this world, you just can't show it all the time, that's all.
- Richie Cunningham: Yeah, but you never get scared.
- Arthur 'Fonzie' Fonzarelli: I know. That's why I'm the Fonz.
- Arthur 'Fonzie' Fonzarelli: [Richie fails to intimidate Frankie and make him back down] I gotta tell you something, Cunningham. I left out one very small detail.
- Richie Cunningham: Tell me quick.
- Arthur 'Fonzie' Fonzarelli: You got no reputation for toughness. Once in your life, you had to have hit somebody.
- Richie Cunningham: That's not a good detail to leave out, Fonz!
