A Jewish man goes and visits a Rabbi about a personal concern of his.
"Rabbi," he says, "I am so upset about my son, I don't know what to do. I raised him a good Jew, taught him the Torah, and instructed him about the Sabbath. Well, I just learned at this last Passover that he converted to Catholicism. Please tell me what I should do to reason with him!"The Rabbi answers: "Funny you should mention this. The exact same thing happened to my son. I taught him everything I know to make him follow in my footsteps and become a good Rabbi like me, and the next thing I know, he converted to Catholicism and became a Priest! I truly don't know what to tell you: maybe we should ask Yahweh for some insights."
To two men started praying: "Yahweh, G-d almighty, Creator of the Universe, please come to our rescue. Our firstborn sons have converted to Catholicism! What should we do?"
A thundering voice responds: "WELL, TELL ME ABOUT IT!!"
