Little Tommy was doing very badly in math. His parents had tried everything—tutors (家庭教师), cards, special learning centers—in short, everything they could think of. Finally they took Tommy to a catholic (天主教的) school.

Finally, little Tommy brought home his report card. He quietly put it on the table and went up to his room and hit the books. His mom looked at it and to her surprise, little Tommy got an A in math. She could no longer hold her curiosity (好奇心). She went to his room and asked, “Son, what was it? Was it the nuns (修女)?”
Little Tommy looked at her and shook his head, “No. ”
“Well then,” she asked again. “WHAT was it?”
Little Tommy looked at her and said, “Well, on the first day of school, when I saw that man nailed (钉) to the plus sign (加号), I knew they weren’t joking. ”
