It is merely irony. Ninjas are not known for carrying guns. These guys are working hard at making their music known. Ninja Gun has a My Space account and can be reached at NinjaGun@hotmail.com
Things to ponder: What exactly is a Ninja Gun? Is it a gun used by ninjas, or perhaps one specifically designed to be used against them? Maybe, if we're lucky, it's a portable cannon that fires ninjas at your target, resulting in grizzly evisceration. But then what happens if you miss, or forget to feed your ammo? Surely such logistical difficulties would hamper the implementation of such devastating weaponry. Alas.
