Little Tommy was doing very badly in math.

Little Tommy was doing very badly in math. His parents had tried
everything; tutors, flash cards, special learning centers, in short,
everything they could think of. Finally in a last ditch effort, they took
Tommy down & enrolled him in the local Catholic School.

After the firstday, little Tommy comes home with a very serious look on his
face. He doesn't kiss his mother hello. Instead, he goes straight to his room &
starts studying. Books & papers are spread out all over the room and
little Tommy is hard at work. His mother is amazed. She calls him down to
dinner and to her shock, the minute he is done he marches back to his room
without a word and in no time he is back hitting the books as hard as
before.

This goes on for sometime, day after day while the mother tries to
understand what made all the difference. Finally, little Tommy brings home
his report card. He quietly lays it on the table and goes up to his room
and hits the books. With great trepidation, his mom looks at it and to her
surprise, little Tommy got an A in math. She can no longer hold her
curiosity.

She goes to his room and says: "Son, what was it? Was it the
nuns?" Little Tommy looks at her and shakes his head. "Well then" , she
replies, "was it the books, the discipline, the structure, the uniforms,
WHAT was it?". Little Tommy looks at her and says, "Well, on the first day
of school, when I saw that guy nailed to the plus sign, I knew they
weren't fooling around."
