Little Johnny was a lazy student and was failing Math badly. His parents had enough of this, so they pulled him out of regular school and enrolled him in the local Catholic school. After the first day, he came home and not a word, and headed up to his bedroom to do his Math homework. He was up there four hours until it was all done. The same thing happened the next day,
and so on. Several days later, his parents came up to his room and asked, “Johnny, what brought this on? Your working your tail off!” Johnny replied,“When I got to my Math class on Monday, and saw that guy above the blackboard nailed to a plus sign, I knew they weren’t messing around”!
