Well, it's funny. When I got the two-book deal after Going Postal , I made enough to quick working in restaurants for a year. So I didn't really have a work environment, and I could just write. Then, last year, I went back to cooking. I don't say it to them, but a lot of times, I'm thinking, nine times out of ten, you're just not weird enough .
Most people are too normal to make it into a book.
But I will do stuff like you mentioned. Sometimes, you work with stock characters. There's a character named Billy in Going Postal . He's a biker dude. He was totally invented.
