Between the iconic main characters and the dozens of offbeat supporting roles, the twisted citizens of Springfield have all given us plenty of quotable lines to use in our everyday lives over the years. But the most recognizable is also the shortest—Homer Simpson’s trademark “D’oh.” This three-letter utterance of annoyance became so universally beloved that it has made its way into both the Oxford English Dictionary and Merriam-Webster Dictionary, being defined as a word “used to express sudden recognition of a foolish blunder or an ironic turn of events.”
