A last thing about all these "The kyuubi was released just 16 years ago, long before Madara and Shodai fought! you dumbass!! hahaha!", hem. Dude, it's nowhere new the Kyuubi attacked konoha just 16 years ago. You're just quoting the manga's frog. How does it feel to be quoting a frog? You must be pretty out of contents to do this. But whatever. I'm of course not talking about the Konoha attack. I'm not that stupid.
The konoha attack being the only one told in the manga up to now doesn't mean the kyuubi appeared only once in a century. Take your sight beyond your nose, thanks.
