What are some bad stories of dumb or negligent things people have done to gear? I'll start one of with one that I heard from a friend: Some guy was a folk and country guitar player for most of his life, and his favorite guitar was an early '60s Gibson Hummingbird that he bought brand new 50-60 years ago. Guy dies in 2012, and his adult son ends up with the guitar. The son doesn't play, but he likes looking at the guitar- it's pretty and every time he sees it it makes him think of Dear ole Dad. So he goes in through the soundhole and mounts the guitar on his wall with a bunch of drywall screws through the back. And there it is to this day. What you got?
