Big Bang Theory Quote
Sheldon: (Coming into the apartment lobby) Uh oh.
Penny: (Standing by the mail boxes) What?
Sheldon: (Still at the doors) I was going to get my mail.
Penny: Okay.
(Sheldon doesn't move)
Penny: Are you hoping to get it telepathically?
Sheldon: I think you mean telekenitically. And no.
(Moves to the mail boxes)
Sheldon: I just wasn't sure of the protocol now that you an Leonard are no longer having coitus.
Penny: God, can we please just say "No longer seeing each other"?
Sheldon: Well, we could if it were true, but as you live in the same building you see each other all the time. The variable which has changed... is the coitus.
Penny: Okay, here's the protocol: You and I are still friends and you stop saying "coitus".
