Everyone mentioned all my favorites here and just to add, I thought Fannucci was somewhat of a comical character! When he passes the puppet show and says to himself "This is too violent for me"! Or when VIto goes to talk to him he says something like, "You gotta lot of balls". Not a knee slapper, but humorous just the same.

The whole way he carried himself as he was at the street feast, as though, he thought himself the "king" of the neighborhood.

I suppose he was in a sense.
