Beer and Weed Bong, the Knockout Challenge

First off, I would like to draw everyone's attention to the old guy at the 1:34 mark taking the hit/chug like a champion. New Yorkers were asked by Complex Magazine to do the Knockout Challenge. Lucky!

The Knockout is basically a beer and weed bong. The site says it's a, 'beer shotgun, water pipe, gravity pipe, and a BEER gravity pipe!'. Fun. You can purchase it online and it's on sale for $30 bucks. I'm sure it's going to be on someone's Christmas wish list. There are four different ways to use this interesting contraption.

These brave people in New York all look like they had a great time trying out the Knockout Challenge.
