The 'How could they have done this' meme, often referred to as 'Who Killed Hannibal?', originated from a 2013 episode of 'The Eric Andre Show.' In the scene, host Eric Andre shoots his co-host Hannibal Buress several times, only to turn to the audience and ask, 'Who killed Hannibal?' or blame an unrelated entity for the action. It became a viral sensation as a way to mock hypocrisy or people who cause a problem and then act surprised or blame others for the outcome. Its versatility in social and political commentary has made it one of the most enduring templates in meme culture.
