Errrrrrrr, well this is one of the weirdest snowboarding edits we've ever seen.

The Japanese riders do come up with some mental stuff. We're not entirely sure what the reasoning behind it is, but they've mechanised a kind of human Mousetrap (do you remember that game?) where riders move, bang into things and fall over to create a knock on effect.

Then, at the end.... Well, you'll have to see for yourself. All we can say is it's totally bizarre but it had us cracking up! Can you tell it's Friday afternoon?
