If you're not totally stoned at this hour then you might not know the TV show Adventure Time exists yet. But if you're a fan of the internet in general, you should appreciate this nod to the Double Rainbow.
It is worth noting that this epiphany made by Jake the Dog happens at the very end of the show during the credits. Because twenty-six different 11-minute episodes were commissioned all at the same time, we're not entirely sure if they were in on the joke or not. I have a good feeling that they are.
