I wanna make the little guy whos struttin his stuff in this video as my avatar ( Preferably an animated Signature but i know i wont get that far haha )

http://www.youtube.com/watch?v=qrsuiD2y3c0&feature=related

So my questions are:

- Whats the best way to get the video off of youtube and onto my comp, i've had youtube downloaders before but they always either were audio only or they were retarded and didnt work.

- Whats a good tutorial of making .Gifs?

Any tips or tricks would be wonderful

Tyty :3
