Not much was left roaming Earth after the Dinosaurs were wiped out. But among the few survivors there was one little creature that crawled out of the ground and gave rise to nearly every mammal on Earth, including us. We meet our great, great, great, great, great...etc!...grandmother and try to give her a name worthy of the ages. Then, comedic force of nature Reggie Watts unleashes some dino-inspired musical mayhem. And Jad and Robert get poetic about the element that introduces death to the Periodic Table: bismuth.
