Big Bang Theory Quote
Sheldon: Just to be clear, do I have to stop saying "coitus" with everyone or just you?
Penny: Everyone.
Sheldon: Harsh terms, but alright. I'll just substitute "intercourse"
Penny: (sarcastic) Great.
Sheldon: or "fornication". But that has judgemental overtones, so I'll hold that in reserve.
Penny: So, how you been?
Sheldon: Well, my existence is a continuum, so I've been what I am at each point in the implied time period.
Penny: You're just coitusing with me, aren't you?
Sheldon: Bazinga!
