An ad for Sky Sport's Rugby Channel with All Black stars Piri Weepu, Cory Jane and Rene Ranger demonstrating why the All Blacks are the best team in the world has attracted a lot of attention worldwide, with more than three quarters of a million views on YouTube.

The ad follows in the footsteps of tennis star Roger Federer's recent William Tell-esque ad for Gillette - where he hits a can off a crew member's head - and gridiron's Fantasy Football "Pick Me" ad from last year, which features the top NFL players.

The question is, are these ads faked?

On the All Blacks video on YouTube, there is much debate around its authenticity.

One believer said: "This is real. It's called skill and consistent practice to a level that a normal human being such as yourself can only perceive as 'Edited' because it is beyond his capabilities and/or potential. Just enjoy their talent."

Another said "haha it's fake,? but who the f*** cares??? it sure was entertaining!"

What do you think? Watch it here.
