Leonard: Okay, I'm going to make this very simple for you. You are not in this relationship, I am. Ergo, you have no say in anything that happens between me and Stephanie.
Sheldon: I'm afraid I can't allow that. Pursuant to Starfleet General Order 104 Section A, you are deemed unfit, and I hereby relieve you of your command.
Leonard: General Order 104, Section A does not apply in this situation.
Sheldon: Give me one good reason why not.
Leonard: Because this is not Star Trek!
