A Jewish man moves into a Catholic neighborhood. Every Friday the Catholics are driven crazy because, while they're grumpily eating fish, the Jew is outside barbecuing steaks.
So the Catholics work on the Jewish man to convert him to Catholicism. Finally, after a lot of pressure and much arguing, the Catholics succeed. They take the Jewish man to a priest who sprinkles holy water on him and says, "Born a Jew, Raised a Jew, Now a Catholic."
The Catholics are ecstatic. No more tempting smells every Friday evening. But the next Friday evening, the scent of barbecue spread through the neighborhood. The Catholics all rush to the Jew's house to remind him of his new diet.
They see him standing over the grille cooking steak. He is sprinkling water on the meat and saying, "Born a cow, Raised a cow, Now a fish!"
