Amy Farrah Fowler:
This project would have us working in close proximity to one another, and there's the vulgar adage that one should not defecate where one eats.

Sheldon Cooper:
My father used to say that all the time. That and um, "who does one have to orally gratify to get a drink around here?" But what does that have to do with you working at the university?

Amy Farrah Fowler:
Sheldon, don't defecate where you eat means don't have a romantic relationship in the workplace.

Sheldon Cooper:
Really!

Amy Farrah Fowler:
Yes.

Sheldon Cooper:
Hnh. I always took it literally. That's why I have never once moved my bowels in this or any restaurant.

Amy Farrah Fowler:
I'm relieved that you don't have a problem with us working together.

Sheldon Cooper:
Not as relieved as I'm about to be. It's a brave new world, little lady. [he heads toward the washroom]
