No one couldve predicted what a sensation the Ice Bucket Challenge would become. The ALS Association wants complete control over ice bucket challenge whenever the three words are being used for charitable fundraising purposes. The move is raising some eyebrows, but its not hard to understand where the ALS Association is coming from. Theres definitely now a very real link between the Ice Bucket Challenge and amyotrophic lateral sclerosis (or Lou Gehrigs disease).
