The Merv Griffin Show Season 9, Episode 6

Jerry

So when I saw George on the street with an 18 pound turkey and a giant box of wine, I thought: ... What a coincidence. We're just about to eat.

Celia

What is that stuff in turkey that makes you sleepy?

George

Tryptophan.* (*footnote - see end of script)

Celia

Ahh.

Jerry

... I think. Have some more wine. (Jerry pours his whole glass of wine into her glass.)
