Personnel on all 24 of Carnival Cruise Lines’ ships, plus CEO Gerry Cahill, took the “Ice Bucket Challenge,” getting doused with ice water to create awareness for amyotrophic lateral sclerosis (ALS).

John Heald, Carnival’s senior cruise director and well-known blogger, was the star of a three-minute video, getting drenched with a garbage can full of ice and water on the Carnival Miracle, then warbling “Let It Go” from the Disney movie “Frozen.”
