A Jewish student was doing well in school in all subjects except
for Math. So his parents decide to send him to a private Catholic
school.
While there the boy came home from school and studied every day. At
the end of the marking period the boy got straight A's. So his
parents asked him, "What motivated you to do so well in
school?"
He replied, "When I saw that guy nailed to a plus sign I knew they
weren't fooling around!"
