If it's for charity work, it won't hurt to get a shower with ice-cold water. Well it would, a screaming LeBron James would counter, but at least it's for good.

Participating in the "Ice Bucket Challenge," which raises money and awareness for amyotrophic lateral sclerosis research, he is seen in this Instavideo completing the challenge on a yacht Sunday and nominating his sons and President Barack Obama, the Bleacher Report said.

Also called Lou Gehrig's Disease, ALS is a "progressive neurodegenerative disease that affects nerve cells in the brain and the spinal cord" causing loss of muscle control, paralysis and death, an ALS Foundation report said. The org is the movement's beneficiary.

"I accept the challenge from Brandon Weems, Kevin Durant, Kevin Hart and DJ Steph Floss," he said in the clip, now liked by nearly 340,000 people on Instagram. "I nominate LeBron Jr., Bryce Maximus and President Obama for the ALS challenge."

Weems is his former high school teammate, Durant is an Oklahoma City Thunder star, Kevin Hart is an actor and DJ Steph Floss is a teammate of LeBron.

The Cleveland Cavaliers returnee found time to accomplish the dare during a vacation in Greece, Cleveland.com said. In the challenge, you either get poured a bucket of ice or donate $100 to ALS research.

James seemed to be one of the few athletes that hadn't done it before he posted his now-popular video, The Washington Post said. The high-pitch scream and the big bucket left no room for speculation that the water was not chilly, NESN.com said.

The challenge is a "charming" mechanism that public figures--like Taylor Swift and Justin Bieber--and their publicists take part in, MTV.com said, adding that it is "catching on like wildfire."

The challenge has "taken over social media the past few days," the Cleveland.com report said, adding that the Cleveland Indians, Cleveland Browns and Ohio State Buckeyes have taken part. Kyrie Irving, Mike Miller and Tristan Thompson, all Cavaliers, have done it, too.

On August 16, Saturday, the ALS Association, the beneficiary of the movement, surpassed $10 million in donations.

It received an "incredible" $11.4 million in donations compared to $1.7 million during the same period in 2013, it said.

LeBron must think "real highly" of himself to address the "metaphysical extension of a chain letter" to no less than the President, SB Nation commented.

But still.

Despite missing the 24-hour deadline set by Durant August 16, at least the reigning MVP challenged Obama, For The Win said.

The President was also nominated by Ethel Kennedy, 86-year-old widow of Robert F. Kennedy, New York Knicks star Carmelo Anthony and the whole Team USA Basketball, Cleveland.com said. MTV.com added Weird Al Yankovic--he also nominated the Dalai Lama and Pope Francis--and Bieber to the list.

James did up the ante, Fox Sports said. Let's see if the King can force the President to submission.
