Justin Davidson from Manhattan, Kansas, figured out a clever and romantic way to incorporate the popular ALS Ice Bucket Challenge into a heart-warming marriage proposal. He got down on one knee with an engagement ring in hand behind his girlfriend Shelby Muha, as she was waiting for him to drench her in freezing water. Shelby accepted his proposal and the two still manage to complete the challenge – and are soaking wet when they finally embrace. Credit: YouTube/Shelby Muha
