An African prince from... let's say, Swaziland (sounds real enough) has had enough of his royal life. So he moves to... let's say, Israel (sounds believable enough), where he gets the job as... let's say, a rabbi (gotta start somewhere), and then...

Wait, that's been done? Natan Gamedze, in real life? You don't say!
