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 earnestly, 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.
