This week is “Shark Week,” on the Discovery Channel, the annual block of shark-centric programming watched by 53 million people last year. As a boy, Marine Biologist David Shiffman was enthralled by "Shark Week" almost from its start in 1988. Bob talks with Shiffman about how, lately, he's become a "Shark Week" critic on Twitter.
