Egg Jousting

I, Ian Jameson, write these words.

I attended an Adiantum event held, iirc, in late spring of 1980, at Hendricks Park.
One of the activities was Egg Jousting.
A truly silly activity.

Take a dozen eggs and hard-boil them.
Entrants select the egg that suits their fancy; if a fundraiser you might auction them off, as was done this time.

You will note that eggs have two ends; Jonathan Swift commented upon this in his *Gulliver's Travels*.
Egg Jousting utilizes this trait.

The defender grasps their egg firmly in their hand.
The attacker proceeds to sharply rap the top of the defending egg with the matching end of their egg, where possible.
So round end vs round end, pointy end vs pointy end, unless one has already been cracked in combat.
Exchanging positions of attacker/defender, repeat until one of the eggs cracks; this is the loser.
Proceed on to the next pair of contestants.

As there are two ends, this can be either single or double elimination.
If double elimination you merely flip your egg end to end to proceed.

It is considered poor form to strike such that the egg is cracked from end to end in the first round if a double elimination tourney.
Proper blow calibration matters.
...And the egg that shatters in such manner might well belong to the attacker.
