just give him all the Naruto CD's you have... it'll get him in no time!
i saw it happening to a friend of mine, after the first day he was hooked up to Haku, but Haku died and he was totally sad for two days,,, and then came the LEE part, so he did the lee stance all the time, and now he's doing the chidori like crazy!

people who love anime can't refuse watching something if you shuv'it up thier ass, downloading is too much of a hasstle usually, so having a complete series and not watching it is a waste...

btw: EP one was the only ep with exactly followed the manga, and it's also a serious episode with action but it also had funnier parts in it.
