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.
