Oh oh, here's another good one for you guys.
So, this was when I was younger, but at one point I was going from my mother's house to my father's. I always carry my games in boxes when I do this, along with other important things such as clothes.
I get there, set my stuff down, and I ask for some help bringing it down to my room. One of my sisters decides to help. She picks up a box with clothing in it. Apparently she caught a whiff of it, and decided that it smelled like smoke. (Which is likely, because my mother chain-smokes.)
So, she decides to go wash my clothes. Sadly, clothes weren't the only thing in that box, and apparently my sister isn't terribly perceptive. So, in goes the games.
Luckily, this was not my entire library. It was only a few, but when I realize that they may have gone into the wash, I ran upstairs and checked. Lo and behold, 5 of my games were found in there. Ruined.
Well, that's a lie, the discs themselves were fine, but the inserts were totally fucked. V_V
