Most people know this... and its not like that the only thing. Cyborgs are not real either. But whats the point in saying this anyway? So you can feel smart? Well ninjas are the hollywood version of eastern assassins. Though they were not called ninjas, they did technically exist.
Video games make you smarter. If it wasn't for Monster Hunter i would have never noticed that 60 was divisible by 1,2,3,4,5,6,12 and 15.
Could have sworn Ninjas did exist in the form of farmers that resisted feudal Samurais or whatever.
They surely did. All of the "ninja" weapons were farm tools they used. They eventually made a martial art based around deception, Ninjutsu. How anyone could actually think ninjas didn't exist is beyond me.
That horse ain't gonna get no deader son. Give it a rest. Go have a sit.
