In this episode, John and Eva stare up at the night sky and get deep. Some of those age-old stoner questions are posed: where are all the aliens? Are we alone in the universe? Could it be that we’re just pets in some zoo run by alien overlords? Does this mean everything we do is meaningless? And what has Jodie Foster got to say about it all? Time to get your SETI on, folks...
