My big brother used to own a Game & Watch, (Helmet) which didn't work when he left home. Needed new batteries. Curiosity killed the cat, so I opened it apart and accidentally broke the screen. It was connected to a circuit in some unfixable way meant its demise. I still lament breaking it, but well, I got to learn something, right? :)
