Last week, Carnival Cruise Lines took up the #IceBucketChallenge, a social media phenomenon that is raising awareness and funds for amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig’s Disease. The #IceBucketChallenge encourages participants to pour a bucket of ice water over their head and then challenge others to do the same or make a donation to fight ALS within 24 hours.

In addition to enlisting the participation of crew members from all 24 “Fun Ships,” as well as Carnival President and CEO Gerry Cahill and shoreside personnel at its Miami headquarters, the company made a $100,000 donation to the ALS Association. The shipboard and shoreside drenchings can be viewed here.

Not to be outdone, Micky Arison, Carnival Corp. & plc chairman and Miami HEAT managing general partner, posted a video of his own icy drenching on Instagram and matched Carnival’s $100,000 donation in the fight against ALS. He also challenged Carnival Corp. & plc CEO Arnold Donald and Miami HEAT President Pat Riley, both of whom were up to the task, undergoing their own frigid dousings. Donald’s video response can be viewed here.

All told, in the just past few days alone, hundreds of Carnival employees have helped raise awareness of ALS by participating in the #IceBucketChallenge with $200,000 donated to this very worthy cause.
