I found a stash of porn in C:\Windows\System22 - it caught my attention because I figured it had to be some malware.

One of the directors backed up his laptop by copying all his data to a network folder that we primarily used for development. Was looking for a specific image and found whole folder of photos of my boss (director's very, very attractive wife) naked. I had to tell him before anyone else found them. He just grinned, asked if I'd seen them, and then deleted them.
