The guys decide today is the day that they dedicate an entire episode to the topic of dinosaurs? Caleb and Alex, both dinosaur enjoyers on varying levels, delve into the ecology 66 million years ago and ponder on what kind of lives the dinosaurs might have lived and how they might have behaved. Also in classic Totally Oblivious fashion, one can't ponder upon the beauties of nature without also wondering how much of it you can destroy with a tactical shovel.
