It's a long joke, so anyone with a limited attention span should just skip to the next post.
It was the middle ages in Rome during the reign of Pope Gelatin the 3rd. A delegation of Roman businessmen came to the Pope and said, "you have to evict all of the Jews from Rome. Their business practices are driving us to ruin. Plus, they are allowed to do business on Sundays. We just can't compete". The pope said, "Gentleman, I can't just evict them for such a reason without warning or cause. But I propose that I send a message to their community challenged them to a debate, and depending on the outcome, either they can stay in Rome or leave the city. Because they are notoriously skillful orators, I'm going to propose to have the debate using sign language"
They agreed that this seemed like a great idea. The pope sent an envoy to the Jewish community with this proposal. The Jews were both horrified and mystified. How were they supposed to conduct a debate using sign language? But it seemed they had no choice. Finally they determined to select Moishe the Tailor as the debater since he was so quick and skillful with his hands.
The appointed day arrived. The pope set out from the doors of St. Peter, long red carpet rolling out in front of him to the center of the square lined with robed clergy all along the route. The Jews were gathered at the far end, and they thrust a very reluctant Moishe forward towards the pope. The pope began the debate. He pointed a forefinger at the sky. Moishe looked at it for a moment and jammed a forefinger into his palm. Then the pope raised three fingers. Moishe raised one finger. The pope gestured to an aide who gave him a carafe of wine and a loaf of bread to hold up Moishe reached into his pocket and brought out an apple, which he also held up. The pope finally spoke out loud. He said, "Moishe the tailor has won the debate and the Jews will be allowed to stay in Rome"
At those words, there was a great hubbub and outcry. The clergy surrounded the pope and said, "your Holiness, how could this have happened? You're a world: renowned scholar, philosopher, and theologian, and this is a man with no formal education". The pope said, "what could I do? His answers were profound and I had no response to them". They said, "what did you say to him?" The pope said, "I pointed to the sky to say, "God is Eternal". But he answered by pointing to his palm, "But God is also imminent". I held up three fingers to say that God manifests Himself in three ways. But he held up one finger to say "Ah, but His essence is ONE". Then I held up the wine and bread to say, "Jesus brought these gifts to conquer sin and evil in the world". But then he held up an apple to say "perhaps, and yet sin and evil obviously still exist in the world". He had a profound answer to every argument. I had to acknowledge that he won.
The Jews came clustering around Moishe. "Moishe, Moishe, how did you win this debate against a Christian with all his strange philosophies and crazy religious beliefs?". He said, "heck if I know". They said, "What was he saying to you?" Moishe said, "he held up a finger which said to me, "All you Jews gotta get outa Rome" And I pushed my finger on my hand to say, "there's absolutely no way we're leaving". He held up 3 fingers to say, "You have three days to pack your bags, abandon your property, and leave the city". And I held up a finger to say, "And I'm tellin' you, not a single one of us is goin' anywhere".
"Then he held up his lunch, I held up mine, and the debate was over".
