Beer bong version 2
Knockout beer bong, is the ultimate party bong. The beer bong is made like a regular bong, with the small change that you can smoke it too. So you get a double buzz when you use it.
Knockout beer bong has become so popular that Snoop Dog itself recommends it.
The beer bong works by drinking the beer, while a friend turns on the joints (or whatever you smoke) when the beer is drunk, you turn the beer bong and smoke further.
With a knockout beer bong, you can both chug beer and smoke get into party mood in no time.
