Big Bang Theory Quote
Sheldon: Was the apple falling on Newton's head, was that just an anecdote?
Leonard: You are not Isaac Newton.
Sheldon: No, no, that's true. Gravity would have been apparent to me without the apple.
Leonard: You cannot possibly be that arrogant.
Sheldon: You continue to underestimate me, my good man.
