When Leonard learns that Penny is dating someone, he become depressed and decides to ask out someone else.
- Mundane Utility: Leslie Winkle is using a 500 kilowatt oxygen-iodine laser to cook ramen.
- Three Laws-Compliant: Comes up when Sheldon is asked if he would want to be told he was really a robot.
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 be endangered?
Sheldon: Well, no.
Howard: I smell robot.
