The What's My Line? episode that airs on GSN tonight — actually, tomorrow morning — features among its contestants a woman named Joanna Lee. Ms. Lee was a writer of sitcoms beginning in the sixties and she was among the writers of The Flintstones. She wasn't the first woman to ever write for animation but she may have been the second. (The first may have been Barbara Chain, who wrote for Crusader Rabbit and Mr. Magoo.)
