Yep, they’re serious. If you’ve ever wanted to be a ninja, you need to move your tail to New York. One instructor has a class that not only teaches you martial arts, but the secrets behind being a ninja warrior. Then you can grab your pirate buddy and finally decide which one is more deadly. Of course to settle the dispute you’ll have to fork out $195 for 90 minutes of training. Then again, if you’re going to invest that much, it just means that you should raise the stakes on the bet over which one will win.
