The Galaxy Brain Humidor refers to the space in which Bret Weinstein and Heather Heying gather to spew unintelligible nonsense via the podcast they call the DarkHorse. They sit in a wooden room, likened to a humidor, peddling their ideas as scientific fact. It is a shifty grift, in that they often use academic speak to disguise their potato-nonsense. If a person were to only half listen, they may be tricked into thinking that Bret and Heather are brilliant researchers, and this is probably why the Humidor has a massive audience of potatoes.
Seen in the background of the Humidor are various items, including a well-maintained houseplant, a sword, various animal skulls, and a sink. It is unknown whether the sink is in working order, and the reason for it's existence is unclear. Similarly notable is the glowing symbol of the DarkHorse podcast, situated in a strange position under a shelf. Seen occasionally are indifferent cats and attention-seeking dogs.
