They do come up with the dumbest things.
A couple of weeks ago my firsties were wearing vampire teeth and running around chasing each other at recess. THey were having a blast! However, they were getting rowdier and rowdier and I was afraid they would end up in trouble (now that I hear about your game, I don't feel so badly) and had to put the kabosh on the game. I really felt bad, but just knew it was going to come to no good end...
