Exploring our network, because I've found that somebody else uses my desktop's hostname, I've found some shared folders on that other machine, open for the public. Curious as I am, I browsed them.
There were some nudie pics.
They were done by my colleague next door.
They were showing him. D'OH!

No, I didn't tell anybody. Don't know how to meet this colleague without being reminded of his anatomy. Must tame my curiosity.

Watch your folders!
