Ding, Ding, Ding! It's Johnny Knoxville vs. Jeremy The Ninja!

You already know Nitro's lawyer-slash-producer Jeremy Rawle, a.k.a. Weird Beard. But did you know dude was also the 1984 National Numchuck Champion? Head over the JackassWorld.com and watch as Johnny Knoxville gives the unlikely ninja an opportunity to show off his martial art skillz.

(Or at least to stand there waving two tiny sticks around ineffectually while Johnny pelts him with rotten fruit.)
