Frasier1993

[Niles refuses to sub for Frasier during his vacation]

Frasier:
Very well. You leave me no alternative but to call in my marker.

Niles:
[nervous] What marker?

Frasier:
Oh, I think you know.

Niles:
You wouldn't.

Frasier:
I would.

Niles:
You can't!

Frasier:
I will.

Niles:
That was three years ago.

Frasier:
I don't recall there being any statute of limitations. I distinctly recall that when you asked me to go out with Maris's sister, you said that you would "owe me one forever."

Niles:
But you only spent one evening with Brie. That hardly compares with what you're asking me to endure.

Frasier:
Oh? Shall I refresh your memory? Midway through the opera her ermine muff began to tremble. As it turned out she had used it to smuggle in her adorably incontinent Chihuahua. Just as I thought we'd reached the low point of the evening I suddenly felt a sandpaper tongue licking my earlobe. Alas it did not belong to little Herv! Fortunately my shriek coincided with the on-stage murder of Gondolfo! Roz will expect you on Monday at two.

Niles:
For your information, Brie had a very tough row to hoe growing up. It's not easy going through life with one nostril.

Frasier:
Did I mention she had a cold that night?

Niles:
...Monday at two it is.
