A solid base for any comedy is just honesty and truth, and it coming from a real place. As surreal as this show gets and is, ultimately, we're dealing with a character that most can't see the way that I can see it.
I am as fond of colorful language as anyone, but I try not to inflict it upon strangers. I suspect many people sense they should have better manners, and need only a nudge. In high school, I was addressed for the first time in my life as "Mister Ebert" by Stanley Hynes, an English teacher, and his formality transformed his classroom into a place where a certain courtliness prevailed.
