Ninjas in history and legend trained for years to develop their acute skills. Their mastery ranged from control of many weapons, like ninja stars or shurikens, poisons, bows and arrows, and of course the mighty ninja sword resembling the samurai's katana. Ninjas are commonly depicted as wearing black, but in fact they would often wear dark blue to blend in with the night, or wear simple costumes that helped them blend into their surroundings. But the ninjas in this video probably wouldn't be admitted to the clan. They don't have very good martial arts skills, are not very graceful, and they are breaking the most important rule of all - ninjas aren't to be seen! These are the Funniest Ninjas Ever!
