My Tae Kwon Do teacher was in a religion class and he was getting bored. The teacher had drawn a circle on the board with G-d's name in the middle, and was writing all the things G-d was. My Tkd teacher wanted to do something drastic, but he didnt want to get caught, so he took a wad of paper and chewed it. When it was wet enough to be an acceptable spit ball, he placed it at the end of his ruler, and took aim at the guy who was sitting a few rows in front of him. When the teacher turned to write on the board, my Tkd teacher fired.
The boy he was aiming at decided to take THAT moment to duck down to pick something off the floor. The great wad of paper flew right over the dude's head, and landed, with a "splat" on the "O" between G and D. The teacher turned around. "Who," yelled the teacher "Dares disrespect G-d?" My Tkd teacher knew that if he didn't fess up, the whole class would get the cane, and some kids had seen him fire the spitball. This meant that he would get a
"blanket party-" I won't go into detail of what that is.
My Tkd teacher meekly raised his hand.
He got sent to the headmaster's office, and he got what was then called: "ten of the best-" meaning ten of the hardest whacks the headmaster could do.
Of, course, my Yae Kwon Do teacher never threw a spitball in religion class again.
Moral of the story?
It could be two things:
-Learn from your mistakes
or
-Never throw a spitball when there is the slightest chance the person in front of you may duck.
