Ha! And THAT is what the sport of curling is all about! We hosted the World Tour a few times at our club and I must say that the Europeans, especially the Swiss, have caught on quite quickly. They have this interesting habit of taking their empty bottles and throwing them under the sofas.
We only found the bottles when we taught them about carrying the sofas onto the ice, so you can play in comfort and order more beer from the bar with your cell phone.
