A very rich man falls ill
A very rich man gets sick. He makes an announcement to get blood to heal. A Jew, seeing the announcement, gives a good heart to his blood. The billionaire offers him a Ferrari, a palace, and other very expensive things.
But unfortunately one day, he falls ill again. He makes an announcement again, and the Jew returns without hesitation to give him his blood.
The billionaire, healed, sends him a letter saying: "Thank you very much for your gift."
The astonished Jew answers by email: "That's all?"
And there the billionaire answers him: "You forgot my friend, I have Jewish blood now!"
