The whole cracky bit is unmitigated brilliance! Really, it's hard to choose, but the one little section that I love so hard, is thus:

Tsume doesn't give a damn that sometimes his mind gets kind of hazy. He's got to do the drills anyway -- claws in! Claws out! Night vision! Nose! Let go! And if he gets angry, even black Kyuubi-rage, she just grabs him by the back of the neck and shakes him out of it.

In matters of chakra level, Naruto is stronger than she is. He's faster, too. Yet he still hasn't managed to dodge her neck-grab-and-shake trick even once. He thinks it might be a secret mom power.
