I think we can agree that we've all found some pretty disgusting things inside (and outside) various computers. My worst was on a system that shutting down for overheating. When I opened the case and got past all the grime, I found that something was entwined in the processor fan and keeping it from running. As I began to free it from the fan, I realized it was a condom.

I don't know why. I don't want to know why.

A bottle of hand sanitizer later and it still creeps me out to think about it.

But I did charge double for the service.
