One of These Things (Is Not Like the Others) is an iconic segment from the legendary educational series Sesame Street, which first premiered in 1969. The song was composed by Joe Raposo and written by Jon Stone, frequently performed by original cast members like Bob McGrath or Muppets like Grover and Big Bird. In the scene, a 2x2 grid of boxes is shown containing four items or characters, and the viewer is challenged to identify the one that doesn't fit the pattern before the song ends. This simple logic exercise was designed to teach children basic categorization and observation skills. In internet culture, this clip has become the definitive 'imposter' meme template. It is used to highlight situations where someone or something is glaringly out of place, representing feelings of social awkwardness, imposter syndrome, or being the 'black sheep' of a group. Whether it is one person wearing the wrong outfit to a party or a single weirdo in a group of professionals, the song provides a perfect comedic soundtrack for visual irony. Example captions include: 'When you lie on your resume but still get the job,' 'Me and the boys trying to act normal in public,' and 'Spot the undercover cop.'
