The cast of SBS's 'Eco Village' took a moment to unwind after an episode of hard work with a good, old-fashioned dance-off!

Girl's Day's Minah and Jang Dong Min were working hard, pounding the dirt flat on the foundation of the house they were building. They noticed that their jumps looked very similar to Crayon Pop's iconic 'piston' dance from 'Bar Bar Bar' - and they couldn't let this opportunity pass them by!

They soon corralled the remaining cast members into an impromptu performance. Check out their antics above!
