Sheldon: I'm glad we're still friends.
Sheldon: Oh, yes. It was a lot of work to accommodate you in my life. I'd hate for that effort to have been in vain.
Sheldon: Just to be clear do I have to stop saying coitus with everyone or just you?
Sheldon: Harsh terms. But all right, I'll just substitute intercourse.
Sheldon: Or fornication. Yeah. But that has judgmental overtones, so I'll hold that in reserve.
