Not my doing, but...
Many, many years ago I worked during my uni holidays for a company. They were looking to get some new computers in, and a sales woman from some distributor came in to demo a rather nice (in the day) Amiga with a full windowing GUI (very new at the time - well before the first versions of Windows were out).
At the end of the demo she said she would leave the machine with us for a few days to evaluate and, as she left, she popped a floppy on the desk with a "have a look at that after I've gone - I think you'll like it".
We were expecting some marketing junk, but it was lots and lots of high-res p0rn images linked into a slide show.
Distracted us so much we never did get round to evaluating the system...
