In this episode, the gang is all back in the same zip code and celebrate by having a long discussion on the origin and extinction of the large mammals from the Cenozoic known as the Megafauna. Somehow this gets.... weird. Meanwhile, James defends the Star Wars Empire, Curt argues why turtles should be ninjas instead of mere heroes, and Amanda confuses Michael Bay with Roland Emmerich. Also, congrats to Dr. Amanda Falk for defending her thesis.

With thesis defenses on the horizon, the group looks to a comforting and familiar topic to escape their morose nerves; mass extinctions. Specifically, they discuss two papers about patterns of survivorship across mass extinction events and use this as a springboard to talking about general macroevolutionary patterns. Also, James fires Curt, Amanda fires James, and Curt decides to host his own private podcast in the middle of the real podcast with special guest Amanda. SPOILERS for House of Cards in the first 30 seconds of the podcast.
