In the USA (at least the part where I'm from) we call it Bocce (pronounced Botchee) Ball. That's a pretty fun game too.
Call them what you will, but I just love the leisure sports. Bocce, Curling, Darts, Horseshoes, Beanbags, Ladderball, Pool/Billiards, bowling, ping pong (table tennis to some)... But yes, I really do love curling.
Mmmm, mad Aussie girls...
