Funny You Should Mention That

So this Israeli sends his son to university in Jerusalem...

The son comes back on holiday and breaks it to his father that he is now a Christian. The father is completely distraught and runs out the back door. His neighbor sees and asks him what is wrong. "My son! He goes to Jerusalem and returns a Christian!" he cries. The neighbor nods his head and says, "You know, funny you should mention that. My son did the same thing. Let's go talk to the Rabbi." So they go to the synagogue and ask to see the Rabbi. They are shown into his office and explain, "Our sons! They both went to Jerusalem and returned Christians!" The Rabbi strokes his beard and says, "You know? It is funny you mention that. My son did the same thing. Let's go talk to God about this." So they go to the sanctuary and begin to pray when suddenly the roof disappears and the heavens open and light fills the room and a booming voice echoes down: "HOW MAY I HELP YOU, MY CHILDREN?" "God! It is our sons, they go to Jerusalem and they come back as Christians!" "FUNNY YOU SHOULD MENTION THAT..."
