The Rugby World Cup is in full swing in the UK, but over in Budapest, Hungary, they've developed a different way of doing things -- a way that involves snorkels, flippers, and a whole lot of water.
In the video above, two underwater rugby teams flail around in a swimming pool while duking it out over a rugby ball. With the extra dimension that's added by players being able to go up and down as well as left, right, forward and backward -- not to mention the fact that people have to keep dashing to the surface for a gulp of air -- the whole thing looks even more hectic than regular rugby.
