The ten-year-old boy was failing math. His parents tried everything to get him to do well in school, but nothing worked. Finally they enrolled him in a Catholic school. From his first day, the boy spent every night poring over books. When his first report card came, he had received an A in math.
"Son," his father asked, "what made the difference in math class? The nuns? The textbooks?"
"Dad, I had never taken math seriously before," the boy admitted. "But when I walked in and saw that guy nailed to the plus sign, I knew this place meant business!"
