The history of computers and software is full of nerdy and obscure jokes well beyond the caricatures of exiting vim. Complier compiler (explain that to most people!) to yet another compiler compiler to bison is one of those.
What are your favourite obscure computer nerd jokes?
Not so much of a joke as a cute story. There was once a programmer with a dog named Biff who would bark at the mailman every time he delivered the mail. The programmer wrote a program to monitor incoming email and beep when you got a message, and named it biff.
