Big Bang Theory Quote
Amy: What's with the blinking?
Sheldon: It's Morse code. So that we can talk about...
(he gestures at Wolowitz)
Sheldon: ...without hurting...
(he gestures at Wolowitz again)
Sheldon: ...'s feelings.
Amy: Sheldon, I don't know Morse code.
Howard: I do. And if you have something to say, you can say it to my face.
Sheldon: Oh. All right.
(he blinks in Morse code)
Howard: I'm a little rusty. Could you say that again?
