Sir David Attenborough is an English broadcaster and naturalist, probably best known for his Life series on the BBC. He's pretty much been the face and voice of natural history programs for about 60 years. When he speaks, people listen.
Since no one in the world understands the sport of curling, Attenborough took it upon himself to figure the sport out and educate the rest of the world. He sure does make the weird sport sound extremely majestic.
