Curling is a sport involving ice, brooms, and originally a rock. It is chiefly played in Canada. Unlike hockey, it is not taken seriously in the United States. Many suspect that it is a byproduct of both the cold Northern climate and the Canadian propensity for beer.
That curling is an Olympic sport baffles Americans who don't consider it a sport at all.

I deleted the file so now it's in the bit bucket in the sky.
