@sozobe,
Someone once described Australian Rules football (which has an ovum-shaped ball) as religious ritual, largely enacted by men, where they pursue the fantasy of returning to the womb, and/or enact some kind of fertility ritual, by attempting to kick said ovum between two giant goal posts representing the open legs and birth canal of the Great Mother.
By that light, round balled football goals would represent one's sperm's success in the greatest race of all?
