The clip comes from the theme music of Thomas the Tank Engine, the children's television character known for cheerful train adventures. Online, a loud version treatment became a simple meme formula, taking a familiar and friendly tune and making it overwhelming through volume and distortion. The French title used for this upload adds to its random, shared-around feel, while the ten second length keeps it focused on the recognisable opening. It remains used because the melody is instantly identifiable, even when the joke is mainly how unnecessarily loud it gets.
