The quote originates in The Simpsons, spoken by Groundskeeper Willie, the Scottish school janitor known for his temper and thick accent. In the scene Willie lists groups at odds with Scots before ending with Scots themselves, turning the rant against his own people. The moment became a widely shared meme template, often paired with text about other groups in conflict with themselves. That adaptable format helped the audio outlive the episode, and the shortened clip now circulates on soundboards as a standalone reaction.
