I once sorta kinda got in trouble for making fun of the "end of the worlders". I was tasked to lead PT back when it was predicted the rapture was going to take place that afternoon at 4pm.

One silly excersize had us leaping into the air with our arms over our heads. I think it was called the "High Jumper". Anyhow, while counting cadence, I called "end of the world" "coming today" "this is practice" "if ya get called away"... Of course one troopie decided this was blashphemy and got all upset. I told her if she was still around at 5pm she could file a complaint. She didn't see the humor in that either. Oh well, 1SG thought it was funny, in a perverse sorta way.
