Pretty insane stuff, It reminds me of when I use to do PC Repair...the crap I would find in the computers was insane. I would take pics to show the customers the before and after pics so they could see how nasty their computers were when they brought them to me.
I have found the same thing some months ago when I was fixing a friends computer but the device wasn't known to him. I was still fixing it when he confronted her about it and she confessed a relationship with someone else on the side. I just gathered up my stuff and left without getting any payment. I just wanted out of there. It was the most awkward 20 min of my life.
But overall the strangest thing I have ever found in buying old desktops was a box of condoms. I have no idea how they got there.
