okay, the theme is judeo-xtianity...

a prominant jewish businessman send his oldest son on a trip to jerusalem, while there the boy converts to xtianity.

the man is aghast and goes to his rabbi for advice. the rabbi tells him that he'd sent his son to jerusalem and he converted to xtianity, so he doesn't have an answer and suggests prayer.

so, the man prays, and a voice from heaven says... y'know its funny, i sent MY son to jerusalem and he converted to xtianity, too.
