If you're not familiar with the Naruto Universe this is a Kawarimi no Jutsu.

It's been a while since I went on an anime binge. I think the original Naruto was the last one I went on with subs but Hulu has the whole of Naruto Shippuden so I figured I'd give it a try. If you only know Naruto from Tunami/adult swim/whatever they're calling Cartoon Network now you're missing out, or at least not getting your full serving or ramen. They hacked the American version something fierce.

So if you like anime give it a look see, if you didn't like the subbed, try the dubbed. It's reading, but with ninjas.
