Once we got a formal complaint from the janitorial staff because one worker had read a message on a server console (back when they were paper) about a child process being aborted.
Haha, that's awesome!
10 years ago I ran a web hosting business; I once got a *very* irate call from a *very* Christian woman, accusing me of being some sort of devil worshiper...
Once I got her calmed down a bit, I finally figured out what had happened: Apparently she had tried to send an email to someone and it bounced, so she got a message from the mailer-daemon!
But it wasn't just the fact that she got an email from a "demon" that upset her; you see, I ran all FreeBSD servers, so at the bottom of the bounce message was a little ASCII art picture of the FreeBSD mascot, horns, pitchfork and all!
She thought we had been embedding Satanic imagery into all her emails or something. She ended up moving over to a "Christian Web Hosting Company" and paying about 3x as much. That company also used FreeBSD servers!
Edit: Funny thing is she used a Mac! She would have really blown a gasket if she realized her email was being sent by Darwin! (Plus Hexley, the Darwin mascot is a platypus with horns and a pitchfork!)
