Richie Cunningham: [after getting locked in at Arnold's] Arnold locked us in!
Ralph Malph: Doesn't he check the bathrooms?
Richie Cunningham: He doesn't clean 'em. Why should he check 'em?
Potsie Weber: Well, there goes the Elvis train.
Ralph Malph: Will you forget about the Elvis train?
Potsie Weber: What's with you?
Ralph Malph: I'm sorry. Guys, I have a confession to make. I get a little paranoid in locked rooms. It makes me very nervous. Once when I was a kid, I got locked in a bathroom, and I flushed a bottle with note in it.
Potsie Weber: Boy, were you a jerk!
Ralph Malph: Yeah? How do you think I got out? I'm telling you, I get very nervous. If this gets me crazy, I'm gonna go nuts!
Richie Cunningham: Ralph, take it easy. It's cool.
Ralph Malph: If it's cool, why am I sweating?
Richie Cunningham: Look, we'll just call up Arnold, and he'll come down and let us out. Anybody got any change? I'm out.
Ralph Malph: I spent my last set on cologne.
Potsie Weber: Can you break a five?
Ralph Malph: I can break your nose!
Richie Cunningham: [checking the phone] Ah, there's nothing here.
Ralph Malph: What about the register?
Richie Cunningham: It's padlocked.
Ralph Malph: Somebody better do something fast. I think I'm gonna cry.
Richie Cunningham: We'll break into the jukebox. It's always filled with change.
Potsie Weber: Wait a minute. Breaking in, I don't that's right, Rich.
Ralph Malph: That's right! That's right! Break in! Break in!
Richie Cunningham: Alright.
[tries to break into the jukebox using a butter knife, to no avail]
Richie Cunningham: Oh, man. It's tougher than I thought.
Potsie Weber: The toilet locked looked easy. Come on, Ralph, let's give it a try.
Ralph Malph: Just don't lock the door. Please don't lock the door.
[he and Ralph walk into the bathroom]
