KP reveals she missed most of the classic high school science dissections, which sends us down a rabbit hole of fetal pigs, frogs, and all the things that somehow seemed normal in science class. We debate the greatness of diet pop, revisit the old "cigarettes in the fridge" era, and learn more than we expected about difficult pregnancies. Plus, Jeff considers the reality of a group hot yoga class, and KP shares an unforgettable story involving a less-than-ideal experience in Mexico. As usual, things go off the rails quickly.
