Young Avi is doing terrible in public grade school. He is getting all Fs and driving his parents to misery. Nothing is helping. He is about to fail out of school. His father Leonard is a friend of the neighborhood priest so he goes and talks to Fr. Jim.
Leonard asks Fr. Jim if Avi can transfer to the local parochial school and everyone agrees that it is a good idea, a fresh start.
Avi transfers and lo and behold he starts bringing home all As. Week after week this goes on and the family is amazed but happy.
Leonard sits Avi down and asks why such a big difference.
Avi tells his father it is simple. At the parochial school his first test was an F and the Principal brought Avi into his office. Avi looks and behind the Principal is a statue of a young Jewish boy, all battered and bruised and with blood nailed on a tree of something like a tree.
What did Avi tell his dad:
"I FIGURED THESE GUYS MEAN BUSINESS!!"
