For my part, I have a tongue-in-cheek interest in him, in that his TV character is an indelible part of my prepubescent brain (he resides there with the likes of Adam West, Julie Newmar, Don Adams, Don Knotts, Jonathan Harris, etc.). The archetypical red-headed, smart-arse, fictional kid grows-up to become an actual, unrepentant troublemaker. It's like seeing Eddy Haskell brought to real life. I can't help but wonder what he is going to do next.
Some people are facinated with gangsters or outlaws, I just sometimes follow some of the TV actors I rememember from my more impressionable age.
