Sheldon: [about Leonard] My theory is that his lack of focus stems from an overdeveloped sex drive.
Beverly Hofstadter: Oh, I don't know where he would have gotten that. Aside from a pro forma consummation of our marriage, his father and I only had intercourse for the purposes of reproduction.
Sheldon: That seems a fairly efficient arrangement.
Beverly: Yes, we think so. We've both done papers on it. Mine from a neuroscientific point of view and his from an anthropological. Mine, of course, was the only one worth reading.
Sheldon: Of course. I would very much like to read about your sex life.
Beverly: Well, it's all online, or you can order it from the Princeton University press.
Leonard: Here is your tea, mother. So, what are you guys talking about?
Sheldon: The frequency with which your parents had intercourse.
Leonard: Swell. If you are lucky maybe she'll show you the PowerPoint presentation.
[Sheldon looks thrilled]
