Little Johnny moves to a Catholic School.

Little Johnny, is a student who is oblivious to religion and is really bad at math.

Little Johnny's parents wanted him to change and go to a Catholic School. After the first day, when Little Johnny arrived home, he went to his room directly. This continued until the first grading, when Little Johnny came home with his report card, he went directly to his room.
His mother, anxious to open the report card, expecting low grades, decided to open it anyway, and was surprised that Little Johhny's grade in math was the highest.

Little Johnny's mom decided to go to his room and ask him about his grades and what has he been doing here.
His mom asked "Wow Johhny, your score is so high! Im proud of you! But what made the difference? Was it the teachers?" Little Johnny replied "No"
"Was it the books?"
"No"
"Was it the new curriculum?"
"No"
"Then what was it Johnny?"
"Well, at the first day of school, i saw this man nailed to the plus sign, then i knew these guys were serious about math, so i studied everyday!"
