This comic imagines Hitler attempting a career in stand-up comedy. The shadowy figure on stage tells a joke: "What's the difference between eugenics and a charity marathon? Well, the second one's a race for the cure!" The audience looks deeply uncomfortable. The caption reads "Hitler's comedy career was brief."

The joke works on multiple levels. The pun hinges on "race" -- in eugenics it refers to racial ideology, while in a charity marathon it means a running race. "For the cure" connects both to charity runs (like Race for the Cure) and to the eugenics movement's horrific notion of "curing" humanity through selective breeding. The comic's humor comes not from the terrible joke itself but from the absurd premise of imagining Hitler as a failed stand-up comedian whose material was, unsurprisingly, too offensive to land.
