Disney CEO Bob Iger proudly participated in the current "Ice Bucket Challenge" to raise awareness and funds for Amyotrophic Lateral Sclerosis (ALS). Sweeping across the internet since July 29th - the Ice Bucket Challenge, is pretty simple in it's concept. If you're challenged, you have a mere 24 hours to dump a bucket of ice over your head and donate $10 to an ALS charity. If you refused the challenge, you have to donate $100 to the charity.
