I've had a stray cinnamon toothpick go *way* up under my big toenail as a kid. It HURT!!!! It left slivers up under there and weeks later I got an infection. That's why I didn't laugh as soon as I read the title of this topic. I winced and curled my toes.
OMG!!!!!
Very clever prank yes, and I'll admit that I thought it was hysterically funny when I first read it, but now not so much. That is something that could have seriously injured my son or any player for that matter & cost them lot.
It's all fun & games until someone gets hurt!
