"Among the gods, there is a dispute as to which one of them originally thought of Christianity; or, as they call it, the Great Leg Pull. Apollo has the best claim, but a sizeable minority support Pluto, ex-God of the Dead, on the grounds that he has a really sick sense of humour. How would it be, suggested the unidentified god, if first we tell them all to love their neighbour, pack in the killing and thieving, and be nice to each other. Then we let them start burning heretics."
