Cramer gets soaked in ALS ice bucket challenge

Cramer takes ice bucket in full suit

CNBC's Jim Cramer donned his best suit to have a bucket of ice water poured over his head Thursday as part of the ALS ice bucket challenge.

The viral sensation has swept across the country and CNBC, with tens of thousands getting soaked to raise money for Amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's disease.

Cramer, who was challenged to take part by Zillow CEO Spencer Rascoff, in turn asked his "Mad Money" viewers to take part.

"I want all the 'Mad Money' viewers who are on Twitter to dump water over everybody, each other, family members and then tweet your pledge, because that's what I'm going to do."

The campaign has turned into a windfall for the ALS Association. The national office has received $5.5 million in donations between July 29 and August 14, compared to $32,000 in donations during the same time period last year. Association-wide donations, which include national and chapter revenue, hit $7.6 million during that time, compared to $1.4 million last year.
