I posted a story a couple of days ago about a civil war shell fired from a ship into Virginia soil that killed the guy who was cleaning it this week.
I would stand back and let some other guy use the backhoe for the rest of the afternoon if I was there....

I remember a story about a teacher who picked up a shell...I think it was WWII ordinance. Had it on his desk as a paperweight. A wasp was bothering him, and he picked up the shell and slammed it on the wasp, which had landed on the desk. Lost most of his hand.
