Seinfeld, Season 7

Peterman:
Elaine, you've tested positive for opium.

Elaine:
What?

Peterman:
That's right, Elaine. White lotus. Yam-yam. Shanghai Sally!

...

Peterman:
I know what you're going through. I too once fell under the spell of opium. It was 1979. I was traveling the Yangtzee in search of a Mongolian horsehair vest. I had got to the market after sundown. All of the clothing traders had gone, but a different sort of trader still lurked about. "Just a taste" he said. That was all it took.

Elaine:
Mr. Peterman, I don't know what's going on here. I am not addicted to anything.

Peterman:
Oh, Elaine, the toll road of denial is a long and dangerous one. The price? Your soul. Oh, and by the way, you have till 5:00 to clear out your desk. You're fired.
