Quote from Donna in Holy Craps!
Caroline: You guys are so much fun to hang out with. Jackie: We really are. Caroline: So what does Cosmo say about me? I'm a Gemini. Donna: Um, okay, the twins. Two people trapped in one body. So you're like a split personality. Caroline: If you ever say that again, I'll kill you. [laughs] I'm kidding. You guys, I'm psycho, remember? Whoo-hoo! Donna: Wow, that was... That was really good. I almost wet myself.
