Kelso: Happy Thanksgiving, Mrs. Forman. This is my date Carol.
Eric: Ms. McGee? Kelso, you're dating my math teacher?
Mrs. McGee: No. No, no, no. We're not dating. We just have a relationship that I thought we agreed to keep a secret?
Kitty: Well, um, welcome. Michael, she is 10 years older than you.
Kelso: Oh, no, no. Nine and five-twelfths. [laughs] She taught me that.
Mrs. McGee: Very good, Michael.
Kelso: Thank you.
Kitty: Okay.
Eric: Kelso, how could you bring her?
Kelso: Oh, relax, man. She's not going to quiz you or anything. But if she does, the square root of zero is zero. She got me with that last night, earned herself a free massage.
