Is there a free youtube downloader I can use with iPod?

I want one where I can put them in iTunes? BTW I have a mac. Any ideas.
Thanks everybody for your answers on the last question as well.

Chosen Answer:

It’s so easy!
First, free download the youtube video with this free tool:

Just get the video url, then you can easily download it.
After that, try this ipod video converter for Mac to convert youtube video to ipod mp4 format.
