You want to see a REAL beast? Look at this guy here, from SASUKE!

Somewhere i heard barrel roll and brought a smile to my face


But yeah, i love these kind of shows, never seen sasuke, but it seems really hard, you can say "oh that looks easy to do" all you want, sh¡t is hard

There were these teenagers from NA, that went to compete in Ninja Warrior. Not sure how well they did though, let me see if I can find any videos. Actually, found this via Wiki:

American athletes

Various American athletes, including gymnasts (and twin brothers) Paul and Morgan Hamm, have competed in Sasuke. Paul made it to the second stage in the 14th and 16th competitions but failed to make it further (in the 14th he cleared Wall Lifting but forgot to hit the button at the end before time ran out, and in the 16th he was eliminated by the Metal Spin). He competed in the 15th competition also, but failed to make it past the First Stage's Warped Wall. Morgan timed out in the First Stage before he could attempt the Rope Climb in the 14th competition, but he did make it to the Third Stage in the 15th, failing there on the Curtain Cling. In the 16th competition, he failed the First Stage's Warped Wall.

Decathlete Paul Terek competed three times. He first appeared in the 17th competition, making it to the Third Stage before failing on the Cliff Hanger. The announcer pointed to his immense size (6 foot 3 and 215 lbs) as a barrier to his advancement. After earning the title of Pro Sportsman No. 1 in 2007, Terek came back to compete in the 19th competition, but failed the First Stage's Jumping Spider. He helped G4 oversee the 2nd American Ninja Challenge competition in early 2008, but he did not compete in Sasuke's 20th competition due to his training for the 2008 Olympic Games in Beijing (though he eventually had to drop out of the running for the Olympics after suffering a torn meniscus in his left knee). He made his return to SASUKE in the 22nd competition but failed on a new obstacle in the First Stage, the Slider Jump he failed the same obstacle in sasuke 24.

Henry Cejudo, gold medal-winning wrestler at the 2008 Olympic Games in Beijing, competed in the 21st competition, but failed the First Stage's Halfpipe Attack.
