This goes on for sometime, day after day while the mother tries to understand what made all the difference. Finally, little Tommy brings home his report card. He quietly lays it on the table and goes up to his room and hits the books.
With great trepidation, his Mom looks at it and to her surprise; little Tommy got an A in math. She can no longer hold her curiosity. She goes to his room and says: "Son, what was it? Was it the nuns?" Little Tommy looks at her and shakes his head. "Well then," she replies, "was it the books, the discipline, the structure, the uniforms, WHAT was it?"
Little Tommy looks at her and says, "Well, on the first day of school, when I saw that guy nailed to the plus sign, I knew they weren't fooling around."
