The Charlie Conspiracy meme, also known as Pepe Silvia, originates from the 2008 episode of It's Always Sunny in Philadelphia titled 'Sweet Dee Has a Heart Attack.' In the scene, a manic and disheveled Charlie Kelly explains a massive mailroom conspiracy to Mac, gesturing wildly at a wall covered in red string and scattered papers. While Charlie believes Pepe Silvia is a fictional employee, a popular fan theory suggests he was actually misreading 'Pennsylvania' on the envelopes due to his illiteracy. The image has since become the universal internet shorthand for over-analyzing a situation, connecting unrelated dots, or presenting a complex, often unhinged, theory.
