In this episode, the gang has a conversation about the various factors affecting total global diversity and how these factors might affect patterns of radiations. Also, Amanda finds a new twitter handle, James drinks a few 11% alcohol beers,  Curt details Winnie the Poo's crack addiction, and the whole podcast is routinely interrupted by random people showing up during the recording. Also, congrats to Dr. James Lamsdell for successfully defending his thesis.
