Eric: The stupid helmet? Why do I have to wear the stupid helmet?
Hyde: Because you're stupid! You can't ask Donna to marry you, man!
Eric: Why not? I mean, come on. We already know that we're gonna be together forever.
Kelso: No, you think that you're gonna be together forever.
Hyde: Remember how you were worried about screwing things up? This is your Bay of Pigs, man.
Fez: Yeah, even in my country we weren't stupid enough to get married in high school. And we eat bugs!
Hyde: Forman, what the hell are you thinking?
Eric: You don't understand, okay? I love her. I was down at the store and I realized- What am I waiting for? We're happy.
Hyde: You don't get engaged when you're happy! What's the point? You do it when your back's against the wall and there's no way out. Like if the girl's pregnant.
Fez: It is settled, then. Eric will get Donna pregnant. I will oversee the proceedings for verification purposes. Ah, but he's so stupid, how do we know he can do it?
