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?"
