Hi Everyone! Happy Presidents' Day! In honor of presidents past, we have decided to do an episode on a topic Nathan has been requesting for a while -- dicks!

Yes, somehow we have gotten around to doing an episode on penises. But as this topic was researched, we found to our surprise that penises are actually kind of interesting! So here, on PART ONE of a two part series on penises, we present to you an evolutionary history of penis!
