It only took me two sentences to get sidetracked back to Kakashi.

Yeah, I kind of noticed that. :) Yes -- I love that Guy as Kakashi's best friend gives you a whole new perspective on Kakashi's weirdness, and vice versa. They're totally funky, but solid. I even felt quite forgiving towards the filler season when they decided to do an ep about Guy and Kakashi, even though it was, well. (Filler season = torch waving arms in the air, saying "omg bring on the war!")
