Cheers, Season 4

[Diane has decided to use Sam's sex life as the subject for her psychology paper]

Diane:
At what age did you have your first sexual encounter?

Sam:
Oh, alright, that's more like it. Okay, uh...[looks at her notes] "Trevor - A Case Study". Who, who's Trevor?

Diane:
That's you.

Sam:
You're not gonna use my name?

Diane:
Of course not.

Sam:
So... I do all the work and this "Trevor" guy gets the credit?

Diane:
Sam this is not your resumé. In a psychological treatise real names are never used.

Sam:
Yeah, but at least I should be able to choose my own name. I mean, how 'bout "Duke"?

Diane:
This is my paper and I like Trevor.

Sam:
Alright, alright. Well, where were we? You, uh, wanted to know about my first time, right?

Diane:
Yes. How old were you?

Sam:
Well, uh, boy, I'm not sure. Uh, I know I couldn't get to her house until the crossing guard showed up. Wow. First time is kind of hard to remember. What about your first time?

Diane:
I'm the scientist, Sam. My first time has nothing to do with this. Now, what about your second encounter?

Sam:
Well, that would be the crossing guard.
