Carla(translated): So when I was a senior in high school, you heard me talking to my friends in English about going on the pill? Marco(translated): No, I just learned English a few years ago. Carla(translated): Well, good, because I wasn't on the pill, and I'm not now. I've never had sex. I hope it's fun.
Carla: And Turk, you don't mind if every now and then Marco and I speak Spanish to each other, right? Turk: Baby, fo'shizzle-dizzle. Do your thizzle, 'cause I'm up out this pizzle. Chach! See, we got our own secret language, too. Eh-ha! Marco(translated): What did he say? Carla(translated): I have no idea. Marco(translated): Jackass!
