The 'I Gave You All the Clues' meme stems from the promotional poster for the 2017 thriller The Snowman. Before the film even hit theaters, the poster’s simplistic, handwritten note from the killer—reading 'Mister Police, I gave you all the clues'—became a target of online mockery due to its perceived lack of tension and awkward phrasing. Social media users quickly began photoshopping the note to reference everything from obvious plot holes in other media to everyday situations where a 'clue' was missed. Today, the meme serves as a sarcastic tool to highlight incompetence or to mock someone who fails to notice a glaringly obvious piece of information that was right in front of them.
