Little known fact, Madara is lactose intolerant. The problem is he didn't realize this up until the fight with Hashirama. You see, Madara ate tons and tons of cheese before their fight, and thus couldn't concentrate because he had to poop really, REALLY bad. Hashirama never actually stole Kurama either, what really happened is that he fainted because Madara kept dropping all kinds of ass. This is also what Madara was referring to when he asked Kabuto if he knew what the secrets to his body were.Cheese. No one can resist the power of Cheese!
