The Patrick Not My Wallet meme originates from the classic SpongeBob SquarePants episode Mermaid Man and Barnacle Boy III. In this scene, the reformed villain Man Ray attempts to return Patrick's wallet, leading to a frustratingly funny exchange where Patrick denies the wallet is his, even when shown his own license. This meme template has become a staple of internet culture, used to illustrate cognitive dissonance, blatant denial of facts, or when someone refuses to admit the obvious truth despite overwhelming evidence.
