Sheldon: Oh, boy.
Leonard: What?
Sheldon: I can't comment without violating our agreement that I don't criticize your work.
Leonard: Then what was "Oh, boy"?
Sheldon: Great restraint on my part.
Leonard: There's nothing wrong with the science here.
Sheldon: Perhaps you mean a different thing than I do when you say science.
Leonard: [makes a change] Okay, how's that?
Sheldon: You actually had it right in the first place. Once again, you've fallen for one of my classic pranks. Bazinga!
