Michael lewis used to be a referee in the big leags of dictionaries, the american heritage. The inter net's been bad for dictionaries - they don't sell the way they used to. I show about the decline of the human referee in American life and what that's doing to our idea of fairness. To day i want to talk about an entire species of refts, one that's nearing extinction, whom no one will miss until it's too late.
