A Jewish man sends his son to Israel to live there for a while. Eventually he returns home and he is now a Christian. The man finds this to be odd and mentions it to his friend.

The friend listens, thinks for a moment and says, "That's odd. I sent my son to Israel as a Jew and he returned as a Christian." So the two of them went to see the Rabbi.

They told the Rabbi the story of how they had both sent their sons to Israel as Jews, and how both sons had returned as Christians. The Rabbi listened, thought for a minute and then said "That's odd. I also sent my son to Israel as a Jew and he returned as a Christian."

So the three of them decide to go to Israel to find out what's going on over there. The arrive and go straight to the Western Wall to pray.

They explain to God all about how they sent their sons to Israel as Jews and how the all returned as Christians." There is a long silence, and then God begins to speak saying, "That's odd . . . "
