I'm not a big radio guy, I don't listen to whatever is the hip new thing.
Stand-up in general is the most raw form of entertainment. There is no pyrotechnics or back-up dancers, it's just live and die by your jokes, that's it.
I don't really go back over my old shows, but I'll see them occasionally, mostly I want to go back and change things about the character as I look at them.
These days, everyone is a writer, producer and movie star. You post something on the web, get enough hits, and suddenly you have TV show.
