Fez: I know something you don't know.
Donna: Fez, you know a lot of things I don't know, mostly because they're disgusting and I don't want to know them.
Fez: True, but this is about Eric. What do you think he's doing every Wednesday night when he's not with you?
Donna: He's taking an at-home Spanish course. He doesn't want to be disturbed, so he locks himself in his room. You know, I think he's self-conscious because he can't roll his Rs.
Fez: Oh, believe me, Donna, he is rolling his ass off.
Donna: Okay, Fez, what's going on? Is there another woman?
Fez: Yes. And it's Eric.
