Ok, I'll go ahead and be lame and post first under my own thread. An actual experience (sort of). I had gotten home from work one day and changed my socks. I'd just thrown the original pair on the floor and thought nothing of it. Couple days later I noticed that same pair, only the inside of them was black. Thing was, those socks were literally just washed the day before I wore them. Beats the hell out of me.
