I don't have any stories about my systems (I was very careful, and somewhat OCD about my stuff), but my fiancee's Super NES has a big hole in the front area of it, where one of her sisters/her stepped on it. The SNES still works, as they all still play their favorite SNES games, but I just saw it as weird.
Also, they were cleaning out their garage for a garage sale, and my fiancee found her old Gameboy Pocket. It's a green one that looks like it's been through just about everything, but it still works. I'll take a picutre of them sometime (the SNES and GB).
