Way back in the late 1970's, when I was a lowly project manager at Data General Mini-Computer Corp, one of the more talented tech writers wrote a "How-To" manual as a joke for our Systems Engineers lucky enough to be helping our customers run our Commercial Advanced Operating System (pronounced CHAOS).
Here is a photo of the title page of my copy. Zoom in and read the finer print, too, and you MicroCode and Software Weinies will get a kick out of the part number (fine print, center of page). It was actually a very accurate and complete manual, but the reader couldn't stop laughing as they went from page to page.
Who says Computer geeks don't have any fun?
This is the same company that had a really good Employee Rock Band that did parodies of just about anything Data General-ish, but mostly made fun of the Sales force. They called themselves "The Talking Propeller-Heads" and have a few videos up on Youtube.

Here's one of their videos. "Ed" was our CEO, Ed DeCastro and "Herb" was Herb Richman, the VP of Sales, and they were our company founders.
