He was very awesome. There was a larger-built man who originally played George on All in the Family, but Sherman certainly was much better in the role there as well as once they had "moved on up". His personality just seemed to make the banter with Archie even more comical. What I thought was the best, though, truly was the way he went back and forth with Florence the maid. That was truly good comedy.
I was not aware that he had passed, but he will be missed. It is hard now to find good, clean family comedy any more.
