"Who Put You On The Planet?" is a memorable quote from the SpongeBob SquarePants episode "I'm Your Biggest Fanatic," where Squidward expresses his utter disbelief and annoyance toward a fan of the Jellyfish Spotters. The scene features Squidward delivering the line with a look of pure disgust, which quickly resonated with internet users looking for a way to react to baffling or nonsensical behavior. Over time, the template has become a staple for roasting 'bad takes,' social media fails, or anyone who seems to lack basic common sense. It is the ultimate 'I can't believe you exist' reaction for the digital age.
