Frasier: Well, Cliff, that's a pretty big step. Outside of Margaret, have you ever had a serious relationship... Or a date?
Cliff: Yep, one time in high school... Wendy Beaman.
Sam: Wendy Beaman. What happened with Wendy?
Cliff: I asked her to go steady. She accepted. And wouldn't you know it, the very next day, I come down with this darn pesky little teenage problem.
Norm: Ah, your face broke out, huh?
Cliff: No. Hysterical blindness.
Sam: What? What did you say?
Cliff: From the Latin, blindis hystericolis.
Norm: Meaning that you couldn't see, or what?
Cliff: Well, I couldn't see whenever she was around, but once she wasn't there, I could see fine. So we got into a big argument about it, we broke up, and as soon as she ran crying out of my life, I could see clear as a bell.
