Big Bang Theory Quote
Sheldon: It's just some quantum mechanics with a little string theory doodling around the edges. That part there, that's just a joke. It's a spoof of the Born-Oppenheimer approximation.
Penny: So you're like one of those Beautiful Mind genius guys. This is really impressive.
Leonard: I have a board. If you like boards, this is my board.
Penny: Holy smokes!
Sheldon: If by "holy smokes", you mean a derivative restatement of the kind of stuff you can find scribbled on the wall of any men's room at MIT, sure.
