Knokkers is one of those rare athletic endeavours 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 2.7kg balls instead of using 8-foot (2.4m) long cue. The original set, seen here, was a labour-intensive installation in Wienecke's Fredericktown, Missouri backyard. But he's working on a portable version - including 2.7kg balls that can stand up to the rigours 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 neighbourhood, 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!]
