If you’ve ever watched “The Simpsons,” “Late Night with David Letterman” or even “The Muppets,” you’re familiar with Nell Scovell’s sense of humor. The writer and director behind these and many, many other television shows joins us to talk about how she made America laugh – and about being a woman in famously male-dominated writers’ rooms. Her new memoir is called “Just the Funny Parts: … And a Few Hard Truths About Sneaking into the Hollywood Boys’ Club” (Dey Street Books).
