Frasier: Oh, Roz. Roz, I wanted to talk to you about this.
Roz: Oh, my God, you still have that?
Frasier: Yes, well, I was glancing at it. I couldn't help but notice the overall score you gave me. Out of a possible five cups of coffee, it was a four.
Roz: Yeah, that's a good score.
Frasier: It's a fine score. But it occurs to me that this presents an opportunity for me to learn something about my performance that might benefit me. So, what might I have done to earn that elusive fifth cup?
Roz: Oh, I'm a tough grader. No one's a five-cupper.
Frasier: Nevertheless, there is a theoretical fifth cup out there. Now, I'm going to put ego aside, this is all about self-improvement. My commitment to "sexcellence" if you will.
Roz: You just lost a cup.
