So one of the experiments they did with their world class ninja was have him surrounded by three archers firing padded arrows.
He of course failed spectacularly and was hit about 20 times before he caught one. Still impressive that he caught one- but then, the ninja remarks that no trained ninja would ever actually be caught in a situation like that.
Well, I too have never been trapped in an empty warehouse with three archers. So I guess eating ice cream, drinking coffee and sleeping till noon has served as all the ninja training I'd ever want.
