Knokkers is one of those rare athletic endeavors that's greater than the sum of its parts. And when the parts in question are jumbo-sized billiards and bowling, that's really saying something.

Invented by former cage fighter Steve Wienecke, Knokkers couldn't be more simple; the rules are the same as 8-ball pool, except you roll the 6-pound balls instead of using 8-foot long cue. The original set, seen here, was a labor-intensive installation in Wienecke's Fredericktown, Missouri backyard. But he's working on a portable version—including 6 pound balls that can stand up to the rigors of constant collision—and plans to distribute it to bars with large backyards and whimsical patrons.


Even if it takes a while to get to your neighborhood, well, that's just more time for you to think up those sexually suggestive puns that defines a true Knokkers legend. [Knokkers via Rural Missouri Magazine via OhGizmo!]
