There were two themes concurrent in Ken's acting: the kind, affable family man, and the self-effacing bumbler. The former was inviting but the later was irritating. His shows (especially F-Troop) were presented during a period in my life where I lacked the wherewithal to reason my way through the nuances but I recognize that (in terms of character building) these stereotypes helped shape my sense of self.
I found myself drawn to insult comedy instead of slapstick because I didn't care for the idea of being being made fun of or disrespected. Think Don Rickles or Paul Lynde. Better to dish it out than to take it.
Oh, and FTR: I couldn't stand Mama's Family
