"An interesting planet." Chatter rolls with Claude, David and Torie. They reveal Claude's latest acting role in the mansion murders podcast and continue working on "The Pitch," Best selling, wicked smart, and very funny Mary Roach zooms in to share "Replaceable You." Forget what you think you know about human anatomy and how we replace/fix/grow new body parts. "Replaceable You" means never looking at a pig the same way again. It's terrific!
