Hyde: Say, chum, where ya headed?
Eric: Just to see my best girl Donna, that’s where. We’re gonna split a soda pop. It’ll be keen.
Hyde: Soda pop, eh? I have something that’s even keener than soda pop. It’s called marijuana.
Eric: “Mari-what-a”?
Hyde: Come. I’ll show you (he throws the flowers away)
Eric: Hyde, you were right. Marijuana’s the bee’s knees.
Hyde: Yep. All it takes is one puff to make you hopelessly addicted.
Eric: I am… hopelessly addicted.
(Fez comes in with a bag)
Fez: Here’s a new shipment, fresh from whatever-the-hell country I am from.
(Donna walks in)
Donna: Gee whillikers, Eric. Where have you been? You missed choir practice.
Eric: Sorry, dollface. But now, thanks to marijuana, I’m incurably insane.
Donna: Well, I’m not gonna let a swell kid like you ruin your life
(she takes the bag from Eric and tries to walk off)
Hyde: (drawing a gun and pointing it at Donna): Not so fast, sister. I need that for the schoolchildren.
Eric: No! (he wrestles with Hyde over the gun)
(Gunshot, Donna falls to the floor)
Donna: Alas, marijuana has ended my young, promising life.
Red: This is what’s happening all over America. And it could happen in your home, or yours, or yours!
Kitty: I just don’t think that’s gonna happen, Red.
