BOBBY’S parents are worried that he’s not interested in learning maths at school, so they decide to enrol him in a Catholic school, thinking that a stricter environment might force him to learn.

So after his first day at the new school, Bobby comes racing into the house, goes straight into his room and slams the door shut. His parents are worried about this, so they go to his room to see if he’s okay. To their surprise, they find him sitting at his desk doing his homework. The parents are delighted, and are even more so when he continues to study hard after school for the rest of the year.

At the end of the year, Bobby brings home his report card and shows his parents. They check his maths score, and sure enough, he’s got an A+.

Thrilled, the mother asks her son: “What changed your mind about learning maths?”

Bobby replies: “Well, on the first day when I walked into the classroom, I saw a guy nailed to a plus sign on the wall behind the teacher’s desk, and I knew they meant business.”
