Naruto: Kawarimi jutsu

I don't understand this jutsu. For example, a ninja that is  attacked can use this kawarimi jutsu and appear as a log and then appear from somewhere else. What happens to the body during this jutsu? Does it teleport the ninja somewhere else?

Okay, nevermind that.

According to http://www.naruto-kun.com/ninjutsu/
the ninja that utilises this jutsu switches his or her body with another object.
If that object is damaged, (e.g. torn, destroyed) what happens to the ninja?

If that object is placed in a small container that would not be able to normally hold a human body, what would happen to the ninja?

he would get THE GOATFINGER!

Fuck disgusting weeaboo.

>>3-kun, that's damned straight, that he'd get the goatfinger.  From her.  Because she gave him the goatfinger.

Frankly enough, goats don't have fingers.

>>7-kun, goats don't need to have fingers, in order to give someone the goatfinger.  It's just a figure of speech.

How dumb do you have to be to throw a kunai at a hokage?

A miniscule KUNAI.

Shine. (shi-neh)

Naruto? What are you, 12?
