OK, now I've seen it all.
Two sports similar in idea, yet far apart in playing surfaces... until now.
Although it's not a proper sport (yet) there is an annual "Eisfussbol" Tournament in Germany made up of German celebrities and athletes.
From what I can gather from the videos below, the combatants wear hockey gear and bowling shoes, which makes their footing VERY slippery... the rest is like soccer... try to get the ball in the set without using your hands.
Seems ridiculous, and well.. after watching you may agree... but it also looks like a lot of fun!
