Johnny was having trouble in math, so his parents sent him to catholic private school.
On the first day he came rushing back home and started working furiously on his math.
He did the same after supper. His mother was impressed and commented to him,
“Wow, Johnny, you’re really working hard!” Johnny looked up and said,
“Well, when I went in there and saw that guy nailed to the plus sign, I just knew they were’nt messing around.”
