Dunno much about AMVs and never really watched them, but I found two which I like particularly and I thought of sharing them with y'all. (-:
Though I think many of you might know those two already, they're quite popular actually.

Naruto AMV - Pretty fly

Sasuke and the 'And Then - Problem'

Second one isn't a real AMV I guess, but I still wanted to post it. It's fun.
