Howard: Sheldon, if you were a robot, and I knew and you didn't, would you want me to tell you?
Sheldon: That depends. When I learn that I'm a robot, will I be able to handle it?
Howard: Maybe, although the history of science fiction is not on your side.
Sheldon: Uh, let me ask you this: when I learn that I'm a robot, would I be bound by Asimov's Three Laws of Robotics?
Raj: You might be bound by them right now.
Howard: That's true. Have you ever harmed a human being, or, through inaction, allowed a human being to come to harm?
Sheldon: Of course not.
Raj: Have you ever harmed yourself or allowed yourself to be harmed except in cases where a human being would've been endangered?
Sheldon: Well, no.
Howard: I smell robot.
