Big Bang Theory Quote
Howard: (on the phone with NASA) Yes, sir, I understand classified. We'll keep it all classified. No one has to know anything about this but you and me.
Penny: What's classified?
Leonard: Howard's space toilet. I'll tell you later.
Howard: (hanging up and sitting down to eat) Well, they've deployed our solution; let's just all hope it works.
Sheldon: I don't see why I have to worry. My career's not hanging in the balance.
(Sheldon smirks at Howard)
Sheldon: That was a joke. It's funny because it's true.
