We really wish we had more to say about this week’s Martial Arts Fail, PotatoNation. But the video and the headline sort of speak for themselves. It’s a ninja who happens to be a witch, a pagan, and an escort (according to her extremely NSFW twitter). In the above video she does some cool ninja moves of dubious real life effectiveness and teaches you how to make a smokescreen.

The below video has some more intense ninja training (sword fights, fire, scaling buildings, throwing stars, and even an arm-bar) and it can be seen after the jump.

This is the jackpot, Potato Nation. It’s the most god-awful Martial Arts Fail we’ve ever seen.

Before you keep reading, watch the video. Our words can’t do it justice. It epitomizes the unfortunate but ever-present fraudulent side of martial arts. For every legitimate school teaching people how to defend themselves, there are 1,000 schools teaching the kind of complete crap in the video.

Did you watch it yet? Because you really need to.

The guy in the video is no martial artist. He’s a conman who calls himself Ashida Kim. Bullshido.net, a website dedicated to exposing martial arts fraud, performed an in-depth investigation on Kim, who’s real name is Radford W. Davis. In addition to peddling this deadly ninja master bullshit, Kim/Davis also mails out phony martial arts certifications. An investigator from Bullshido even managed to get a certificate saying he was a black belt in Vale Tudo from Kim/Davis.

Feeling like you wanna punch this guy yet? Well, he’s got a plan for that. It’s called the $10,000 Challenge, which includes such stipulations as posting a $25,000 “appearance bond” to make sure you don’t skip town as well as paying Kim $10,000 to show, as well as footing the bill for his lodging and food. Nice.

Oh, and this guy also claims he can levitate. Watch the video of him attempting to do so after the jump.

This week’s Martial Arts Fail was going to re-visit Master Wong—the man who warned us that eye pokes would result in our families being murdered. But midway through the week we received a tip from CagePotato contributor Adam Ackerman. When we watched the video he sent us, we knew it had to be this week’s Martial Arts Fail.
