I've spent hundreds of hours over at tvtropes.org pouring over their character descriptions. The Barnum, for instance, is a kind of trickster character who lives by exploiting greed. Equally interesting--especially to those watching Under The Dome--is the Honest John's Dealership trope.
As I was searching through the forest of descriptions I came upon something called The Five Bad Band that (suitably modified) I'm going to use in my next story. I was so excited to find it, I had to share it.
