In the days when Sussman was a novice Minsky once came to him as he sat hacking at the PDP-6. "What are you doing?", asked Minsky. "I am training a randomly wired neural net to play Tic-Tac-Toe." "Why is the net wired randomly?", asked Minsky. "I do not want it to have any preconceptions of how to play." Minsky shut his eyes. "Why do you close your eyes?", Sussman asked his teacher. "So the room will be empty." At that moment, Sussman was enlightened.


A student, in hopes of understanding the Lambda-nature, came to Greenblatt. As they spoke a Multics system hacker walked by. "Is it true," asked the student, "that PL-1 has many of the same data types as Lisp?" Almost before the student had finished his question, Greenblatt shouted, "FOO!", and hit the student with a stick.

A famous Lisp Hacker noticed an Undergraduate sitting in front of a Xerox 1108, trying to edit a complex Klone network via a browser. Wanting to help, the Hacker clicked one of the nodes in the network with the mouse, and asked "what do you see?" Very earnesty, the Undergraduate replied "I see a cursor." The Hacker then quickly pressed the boot toggle at the back of the keyboard, while simultaneously hitting the Undergraduate over the head with a thick Interlisp Manual. The Undergraduate was then Enlightened.
