[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?
