Why do all these stories involve percussion or props? Seems like there should be some wind-related accidents as well...
Oh, actually, I didn't see this happen, but I heard that some euphonium kid accidentally left his instrument in the stands after a football game and forgot about it for some time. Since these were electronic stands that folded up, between the time he left it there and the time he remembered it, it had been flattened lol. I'm sure the school was sure happy about that one...
