Playing beerpong with water is lame. Also, referring to beerpong as beirut does not make you not a noob, it probably just means you are either from the east coast or learned to play in some gay ass frat house.
Also that youtube vid is the American dream right there. Have a completely unoriginal idea (like making beer pong bigger), then making LOTS and LOTS of money off it. Fair play to them. I'm assuming they sell the buckets and balls and such on their website.
