The eldest son of Duck Dynasty stars Willie and Korie Robertson, John Luke, accepted the ALS Ice Bucket Challenge from his father.

Hundreds of celebrities and sports stars across the US are getting soaked in the name of a good cause.

The Ice Bucket Challenge is aimed at helping strike out ALS (Amyotrophic lateral sclerosis), commonly known as Lou Gehrig’s disease.

People who participate are getting doused with ice water and then challenge other to do the same to raise awareness for the disease.

Willie Robertson and his trademark beard are the latest to take the challenge. Friends dumped water on him from the roof of his West Monroe, Louisiana, business, Duck Commander. He challenged his son, John Luke, professional baseball player Adam LaRoche and NFL player Matt Light to go under the bucket.

John Luke Robertson accepted the challenge and nominated his friends.
