I did have a strap come loose and a perfectly good Aria hit the floor breaking the neck once, thats as cloce as I ever came to it. I have felt like trashing a few guitar salespeople over the years though.
I smashed a Kramer once in the 80's. After a stage mishap that broke the headstock (it was still playable because of the locking nut) So at the end of the show, I smashed it. It's a good way to give yourself tennis elbow.
