A Jewish man took his Passover lunch to eat outside in the park.
He sat down on a bench and began eating. Since Jews do not eat
leavened bread during the eight day holiday, he was eating Matzoh,
a flat crunchy unleavened bread that has dozens of perforations.
A little while later a blind man came by and sat down next to him.
Feeling neighbourly, the Jewish man passed a sheet of matzo to the
blind man.
The blind man handled the matzo for a few minutes, looked puzzled,
and finally exclaimed, "Who wrote this crap?"
