We are fortunate indeed to have in our virtual playground someone like Sam Ryan who has the wisdom to go to the needed lengths to document the essence of the prototypical Junkyard Sport, Calvinball.

I find myself with no option other than to quote:

"1. All players must wear a Calvinball mask (See Calvinball Equipment - 2.1). No one questions the masks (Figure 2.1).

"*IMPORTANT -- The following rules are subject to be changed, amended, or dismissed by any player(s) involved.

"1.2. Any player may declare a new rule at any point in the game (Figure 1.2). The player may do this audibly or silently depending on what zone (Refer to Rule 1.5) the player is in.

"1.3. A player may use the Calvinball (See Calvinball Equipment - 2.2)in any way the player see fits, from causal injury to self-reward.

"...1.9. Any rule above that is carried out during the course of the game may never be used again in the event that it causes the same result as a previous game. Calvinball games may never be played the same way twice..."

Thanks for this find go to Eric Zimmerman, himself, and mine, too.
