The Korean Plank Act in Cirque du Soleil uses this same equipment, to great effect.

If you have the opportunity, check out the episode of Solstrom called Wind of Freedom which shows it off particularly well

I was going to guess Cirque du Soleil just because these skills don't quite fit anywhere else.

This could become an olympic gymnastic competition one day... similarly to how people watch figure skating, secretly hoping to see them fail.

also, this might be the first 'vertical video' that was actually appropriate.

*FTW - the hang time they get on that thing is incredible.

Adding video to channels (Ftw) - requested by shveddy.

Oh, it is Cirque Du Soleil, Dave of dailypicksandflicks.com posted it there with this description:

Cirque Du Soleil acrobat David Rimmer training a teeterboarding routine with his partner Steph. Insane stuff! (via).

Hmmm, what would happen if you tried these routines on a see-saw at the local park??

Get Jackass to do it. Might finally be rid of him.

Seriously, part of the effect is the bending of the board, a seesaw (if you can even find one anymore thanks to nanny-ism) is designed to be rigid.
