Long ago in Seattle, I used to sell Bill Irwin airline tickets … yes, the neo-vaudevillian clown Bill Irwin. And now he’s “the scary new serial killer on CSI” Bill Irwin. My husband David didn’t know his work, but this clip from an appearance on the Cosby Show is pretty representative of what he was doing then. His current work on CSI is absolutely chilling, especially as he’s seated and mostly immobile the entire time.
