I think my quote has been misunderstood and want to clarify. I said
Talking about the stern boss it's just a role he (John) is being a ham about when he hosts and it's all in humor, like pretending to be annoyed at Teresa. It had nothing to do with Pete and certainly not Oliver.
In the show after Bob died John spoke about how Bob used to ham up the role that everyone was "picking on him," but off air Bob was quite able to stand his ground and full of rebuttals. I think John wanted everyone to know that Bob was just being a ham for the fun of the show and he was genuinely liked.
It's the same thing, John is a GREAT host because he tries to make it fun. Just like when Craig uses his anchorman voice to do the weather. Please don't take what I said so seriously.
