A Jewish man moves into a strict Catholic neighborhood. Every Friday afternoon, the Catholics practically go crazy because while they're eating only fish, the Jew is in his backyard barbecuing steaks. So, the Catholics work on the Jew to convert him.
Finally, by long endurance, the Catholics succeed. They take the Jew to a priest who sprinkles holy water on the Jew and intones, "Born a Jew. Raised a Jew. Now a Catholic."
The Catholics are ecstatic; No more delicious, but maddening, smells every Friday afternoon! But come the following Friday, the scent of barbecue wafts through the neighborhood. The Catholics all rush to the Jew's house to *remind* him of his new diet. They find him standing over the sizzling steak, knife in one hand, his other hand dipping in water. He sprinkles water over the meat saying, "Born a cow. Raised a cow. Now a fish!”
