This guy told me that it was impossible to defend against an attack when someone stands on one leg with their arms out and then jumps and kicks while landing on the other leg. He called it a "swan kick" or something, but I'm pretty sure the dude was crazy since he spent most of his time trying to catch flies with chopsticks.

"Have you ever thought of incorporating ninjitsu into your MMA?"
I've heard a lot of the claims mentioned in this thread. They were more prevalent before UFC 1, but they still pop up from time to time.
A common one is the aforementioned: "[TMA style] would work great in MMA but it's against the rules." When I ask them what particular technique they thought was against the rules, they usually answer something that is, in fact, NOT against the rules. The most recent example was breaking limbs standing aikido-style.
