A Catholic priest and a Rabbi are talking about

A Catholic priest and a Rabbi are talking about job prospects. 

"Well," says the priest, "there's a good chance that I'll be the next bishop - maybe within the next couple of years." 

"Bishop!" marvels the Rabbi, "very nice. And after that?" 

"Oh, I don't know, I suppose it's possible I could become Archbishop...given luck and god's blessing." 

"Very nice, very nice; and after Archbishop?" 

"Ha! Well, you know, it's Cardinal after that, but it's really very unlikely. But in theory, I could become a Cardinal." 

"Lovely!" enthuses the Rabbi, "the scarlet would suit your complexion. So what's after Cardinal?" 

The priest smiles: "After Cardinal? Well, it's Pope - but I'm hardly likely to become... hmmm, oh I suppose it's just possible. If a Pole why not an Englishman again? Yes, I could just become Pope." 

"Splendid! And after Pope?" 

The priest looks at him in surprise: "After Pope? There's nothing after Pope! I mean, there's just god above the Pope - I can't become god." 

"Why not? One of our boys made it."
