Penny: Can I ask you a question?

Sheldon: Given your community college education, I encourage you to ask me as many as possible.

Penny: Yeah. Well, my question is, and I’m pretty sure I know the answer, is this your first date?

Sheldon: That depends. Does square dancing with my sister at a Teens for Jesus Fourth of July hoedown count as a date?

Penny: No.

Sheldon: Then, this is my first date.

Penny: Okay. Well, then, there’s a couple of things you should probably know.

Sheldon: I have a master’s degree and two doctorates. The things I should know, I do know.
