Pasche Eggs (Part III)

The one Pasche Egg Extreme Sport that's still popular round here on Easter Sunday & Easter Monday is Egg Dumping. This has nothing to do with the EC offloading surplus agricultural produce onto some hapless third-world chicken farmers.
Egg Dumps usually take place at pubs, clubs and parties. You'll need a lot of eggs and some friends. Taken an egg each (in the commercial version you buy an egg for a pound, winner takes all). Pair up. By some obscure method (a toss of a coin usually works) decide which contestant is to be 'over' and which 'under'. Advanced Egg Dump Game Theory states there's a small but measurable advantage to being 'over'.
What follows is basically egg-conkers. 'Under' grasps their egg and holds it steadily, sharp end up. 'Over' holds their's above it sharp end down & smashes it into 'under'. The winner is whoever's still got an unbroken shell. Loser gets to eat their egg. Winner goes on to face the next opponent, with the advantage of being 'over'. Last egg standing wins.
