The Spanish Christmas Lottery, known as El Gordo, is held every 22 December and is famous for its long draw in which children from Madrid's San Ildefonso school sing out the winning numbers and prizes. In 2016, number 66513 won the top El Gordo prize, worth four million euros per series, and the announcement became a familiar festive sound across Spain. Short clips of the chant are now reused online whenever creators want an instant Christmas, lottery or big-win cue, keeping a long-running national tradition alive in memes, videos and holiday edits.
