I have never heard of this before but Seattle Times reported on it a couple days ago. It is, from the description: "Nepalese students of Himalayan agriculture college play in mud water in a paddy field to celebrate the National Paddy Day in Badegaun village, Lalitpur, Nepal, June 29, 2016. More than 100 students and teachers of Himalayan agriculture college participated in the National paddy day by planting rice and playing in mud water as Nepal is celebrating National Paddy Day with various event. On this day, known as Asar Pandra, farmers begin the annual rice planting season and mark the day with various festivities such as preparing rice meals with muddy water, mud being a symbol for a prosperous season. The agricultural sector contributes about 60 per cent to Nepal's gross domestic product"

Looks like from at least this picture there is some potential??
