Church camp scorpion.
Just a little brown scorpion tucked underneath a lacrosse ball. I got him at church camp where the boys of my cabin would go on scorpion patrol every night as I gave them an inservice on insects, wasps and arachnids. We killed a couple hundred scorpions that week and a dozen Black Widows. I lined up the big gallon jugs along the front wall and we had a few specimens of everything interesting.
Only had one kid stung- against advice, orders, reason. The teenage stuff. He tried to stash on in a ziplock bag to take home.
