Perceptron: Greetings. I am Dr. Perceptron. Let me give you something to help you relax.
(He presses a button and Fry gets an electric shock)
Fry: Look! There's been a terrible mistake. I'm a human being. See? I'm all squishy and flabby. Also, I complain a lot.
Perceptron: Yes, you do. You need to relax more. (He gives Fry another shock) Terrific. Now, consider the following: You were admitted to this robot asylum. Therefore, you must be a robot. Diagnosis complete.
Fry: I do other human stuff! I age! See?
