Blank-Eyed Girl and Pizzagate
The episode is about Jake and Finn eating at a pizzeria with a radio playing a conspiracy, Alex Jones-type host.
The conspiracy is about appearances of a strange blank eyed girl & Jake dismisses it as bologna. Finn tells him to have an open mind & Jake refuses.
On their way home they see the girl & proceed to get creeped the eff out. She follows them and haunts them inside the house so the two decide to do some research at the library.
When they walk in, Jake explicitly says they are going to get down to the hard truth . . . From a secondary source. Behind a book labeled "Creepy stuff" a hidden compartment lies with a library worker.
The worker relays the information about Blank-Eyed Girl, saying it's only a physical manifestation of what they WANT to see as opposed to what's actually there.
Finn and Jake go back to the house with hopes to make the, at this point in the story, 6 blank-eyed girls disappear. As soon as they open the door, they're all staring at them - Jake tries to avoid them by walking around the living room but is then surrounded by the children, and he tells himself to think happy thoughts.
A thought bubble shows the inner workings of his mind go from Lady Reinicorn turning into a blank eyed girl, then Bemo turning into a blank eyed girl, and then a Pizza pie that turns black, zooming out as the right eye of the blank-eyed girl.
Jake shouts, "okay! They're creepy, you win!" and with those words said, the girls drop their eyes, shed three layers and float out the window as a cloudy phantom.
Now the weirdest thing about this is is that it aired January of 2016 - well before the Wikileak.
