Eric: Oh, my God. Call Walter Cronkite. My girlfriend has her pants on.
Donna: Okay. You're behaving like the biggest baby. What's your problem?
Eric: What's my... My problem is, it's your... butt. It's our butt. It's my butt.
Donna: Eric, it's my butt. And when I showed it, it was funny. And you should be glad that you have a girlfriend who's cool enough to moon.
Eric: Well... yeah, okay. I mean, you're right, but... you know what? Once the jocks and the guys with the Firebirds see it, you know, they're just gonna totally want you.
Donna: Oh, no. And with my weak-willed girly mind, I'll go, too. You're such a bonehead.
Eric: Yeah, I know. Okay. It's great. But, you know, in the future, would it kill you just to have a smidgen of modesty?
Donna: [laughs] Oh, my God. [laughs]
Eric: What... What's so funny?
Donna: You're a prude.
Eric: I am not.
Donna: Yes. You're uptight, like a little pilgrim.
