Tom Lehrer?  I have the boxset.  Gotta love 'Poisoning the Pigeons in the Park'...
The idea of rank in the pantheons probably needs formalising, yes.
King/Queen (or a pair of Queens 

 - maybe safer to say Ruler and Consort) first and second, then... Underworld/War/Love(Lust)/Wisdom, in that order.  God of Thunder probably comes pretty high on the list, come to think of it.
It'd be nice if the head of a pantheon could set up his own list of ranks and portfolios, but that would require a neutral admin figure.  Might be good, though.
