The Ententanz, literally the duck dance, was written by Swiss accordion player Werner Thomas in the 1950s and grew into one of the world's most played party tunes. English-speaking countries know it as the Chicken Dance, complete with the beak, wing and tail-wagging moves. Oktoberfest bands carried it across Europe while wedding DJs and sports arenas made it a crowd ritual in America. Decades later the bouncy melody still fills dance floors, which is why short clips of it circulate as a go-to funny dance cue online.
