Never anything I liked like gameboys or a DS. But just about every day I ended up leaving my Math textboo on a random table outside at school or in a random classroom. It almost ALWAYS ended up back in my Math professors room except for the one time when it sat outside on the bench I left it on when I took the bus home. ;_; I am glad it hasn't really happened with any electronics apart from a crappy phone or two... But hey, that worked out because I got better phones both times. :p I had to wait a little bit, but it was perfectly fine with me!
