Lana: I think... I want Kirby to get a C.
Frasier: What? You said all he had to get was a passing grade!
Lana: Well, that's before you went behind my back. And just for arguing, I want a B!
Frasier: That's crazy!
Lana: Well, keep talking mister, and I'll go for an A!
Frasier: All right, all right, a B it is.
Kirby: [entering] What am I doing again? Oh yeah, I'm washing up. [exits]
Lana: Okay, a B minus.
