I sat next to Bill Nye at a dinner last year. I asked him how he got so good at being on camera, and he told me when he was growing up, he always wanted to host, but he didn't have a camera. So, he [music] got a cardboard box and put some PVC pipe in it and put it on a shelf in his room, and he would [music] talk to it every day because he knew that at one point if I got the opportunity to be on camera, I'd [music] have to be really good at talking to a circular black hole. I thought that was fascinating.
