A רב was traveling on El Al, when his seat-mate asked what he did for a living. “I’m a rabbi,” he said. “Well,” said the man condescendingly, “I was born Jewish. I don’t know much about it, but I presume you could sum it up in one sentence: ‘Do unto others as you would have others do unto you.’” The rabbi smiled, then said, “And what do you do for a living?” “I’m an astrophysicist,” he replied smugly. “Well,” said the rabbi, “I don’t know much about it, but I presume that I too, could sum it up in one sentence: ‘Twinkle, twinkle, little star ‐‐ how I wonder what you are.’”
