A king-of-the-hill type game played on a mound of dirt put on a baseball diamond before it is raked out.
A shovel is stuck on the top of the dirt mound, and everyone playing gathers around home plate. A prophet is declared, this should be the most reasonable person of the group. Then everyone runs, jumps, kicks, punches and does whatever possible to be the first to claim excaliber from the top of the dirt pile. Once excaliber is claimed, the prophet may decide to reset the game, or continue with king-of-the-hill while the king has a shovel to defend him or herself.
"Damnit, Sherman won excaliber again! Joel's in the hospital now!"
