Rape Ape
The Rape Ape meme began in the episode of the Weird Things Podcast, Monkey Man Begins, when Brian Brushwood, Justin Robert Young, and Andrew Mayne were discussing what would drive them towards becoming a vigilante, and how they would slay their victims.
The discussion was quite tame to begin, Andrew was saying that he would train a circus monkey to kill criminals, and that he would drive the chimp around in a truck reading "Happy Monkey Delivery Service" and allow him to go apeshit (get it?) on the scum of the earth.
When Brian slipped up and said "rape" instead of ape, he just went with it, saying "Well, he's going to rape the victims before he kills them, right?", which ensued in hilarity. Other things were said, and a new with great power comes great responsibility was coined by Justin with "If they deserve to be killed, then they should deserve to be raped by a chimpanzee and killed".
Rape ape was mentioned again in Zos Braining Zos, as was his brother Shave Ape.
