The Big Bang Theory, Season 3

[at the site for Sheldon's online date]

Amy:
Excuse me. I'm Amy Farrah Fowler, you're Sheldon Cooper.

Sheldon:
Hello, Amy Farrah Fowler. I'm sorry to inform you that you've been taken in by unsupportable mathematics designed to prey upon the gullible and the lonely. Additionally, I am being blackmailed with a hidden dirty sock.

Amy:
If that was slang, I'm unfamiliar with it. If it was literal, I share your aversion to soiled hosiery. In any case, I'm here because my mother and I have agreed that I will date at least once a year.

Sheldon:
Interesting. My mother and I have the same agreement about church.

Amy:
I don't object to the concept of a deity, but I'm baffled by the notion of one that takes attendance.

Sheldon:
Well, then you might want to avoid East Texas.

Amy:
Noted. Now, before this goes any further, you should know that all forms of physical contact up to and including coitus are off the table.

Sheldon:
May I buy you a beverage?

Amy:
Tepid water, please.

Howard:
[to Raj, seeing their "experiment"] Good God, what have we done?
