Kelly Kahl has been scheduling CBS' prime-time programming for two decades, but he knows that his job still remains a mystery to most people. "Scheduling is a weird thing: You get it or you don't. There's a certain attraction to this job that's hard to explain," he says. "People look at what we do, and they shake their heads and are like, 'I don't get what you do. You show up in May and put a little schedule together for the fall season. And then what?'"
