One night, a Jewish couple invited their young friend, non-Jewish, over for a meal.  One of the dishes presented was Matzoh Balls.  Once he heard what it was, he seemed very unsure of himself as he watched the delicious soup.

Understanding, the couple told him that he only had to try a little bit, and, if he didn't like it, he didn't have to finish it.

He took a little, biting just a little bit, then smiled as he started to slurp the rest of the soup in, finishing it all in record time. "Wow, that was great...."

"....What does the rest of the Matzoh taste like?"
