Matzoh for Lunch (humor)

A Jewish man took his Pesach lunch to eat outside in the park.  He sat down on a bench and began eating.
A little while later a blind man came by and sat down next to him.  

Feeling neighborly, the Jewish man passed a sheet of matzoh to the blind man. The blind man ran his fingers over the matzoh for 
a few minutes, looked puzzled, and finally exclaimed, "Who wrote this nonsense?"
