I recall a teacher telling us (with some scepticism, to be fair) that St Malachy had predicted only four more popes before the end of the world and that amongst them there would be one Irish pope and one black pope (I know, I know... a black pope, an Irish pope and a greyhound walk into a bar... bear with me people! This is a serious theological discussion, we're having!).
Anyhoo... my point is: we're down to the last pope now and we still haven't had an Irish or a black pope.
So my money is on Paul McGrath to be the next pope.
