After the first day, little Tommy came home with a very serious look on his face. He didn't even kiss his mother hello. Instead, he went to his room and started studying. Books and papers were spread out all over the room and little Tommy was hard at work. His mother was amazed. She called him down to dinner and to her shock, the minute he was done he marched back to his room without a word and in no time he was back hitting the books as hard as before. This went on for some time, day after day while the mother tried to understand what made all the difference.
Finally, little Tommy brought home his report card. He quietly laid it on the table and went up to his room and hit the books. With great trepidation, his Mom looked at it and to her surprise.... little Tommy got an A in math.
She could no longer hold her curiosity. She went to his room and said:
"Son, whaaaat was it???? Was it the nuns??"
Little Tommy looked at her and shook his head, "no."
"Well, then", she replied, "was it the books, the discipline, the structure, the uniforms???? WHHHHAAAATTTT was it????"
Little Tommy looked at her and said, "Well, on the first day of school, when I saw that guy nailed to the plus sign, I knew they weren't fooling around."
