This week Craig Benzine takes a first look at the judicial branch. It's pretty easy to forget that the courts, and the laws that come out of them, affect our lives on a daily basis. But how exactly these decisions are made and where each law's jurisdiction starts and ends can get pretty complicated. So complicated in fact that you may want to smash something. But don't worry, Craig will clear the way.

In which John Green teaches you about Homer's Odyssey. If it was Homer's If Homer was even real. Anyway, that stuff doesn't really matter. John teaches you the classic, by which I mean classical, epic poem, the Odyssey. The Journey of Odysseus as he made his way home after the conclusion of the Trojan War is the stuff of legend. Literally. John will teach you about the double standard in Greek culture, Odysseus as jerk/hero, ancient PTSD, and cycles of violence. Also, there are no yogurt jokes. So think of that as a gift.
