It's party time, as participants dance in the mud at South Korea's Boryeong Mud Festival.
An estimated 2 million people from around the world converge on Boryong City, each of them ready to come clean and leave dirty.
When the festival began, in 1997, its aim was to promote Boryeong's mineral-rich mud used in skincare and beauty products.
Most of the Boryeong Mud Festival festivities are held at Daecheon Beach, where it's bikinis galore.
Boryeong City has less than 100,000 residents, and the nine-day festival pumps an estimated $53 million into the local economy.
