There’s a South Park episode where Eric Cartman takes credit for a joke. The episode is particularly funny and shows the degree to which people can be clueless about certain nuances in life. Eric Cartman engages in extreme “mental gymnastics” when denouncing facts or even pure reason. The show constantly emphasizes that Eric Cartman is a psychopath. He acts in a manner we can only interpret as evil, but throughout the series he remains unaware of his insanity.
