BOSTON — You can add Celtics legend Larry Bird to the growing list of celebrities to accept the Ice Bucket Challenge to raise awareness for ALS, or Lou Gehrig's disease.
For those who have been under a social media rock, here's how it works:
Those who chose to participate dump a bucket of ice-cold water over their heads and post it to at least one social media outlet (Twitter or Vine, for example). After getting soaked, they then challenge three others to either do the same within 24 hours or make a donation to the ALS Association.
It began in support of former Boston College pitcher Pete Frates, who is fighting the disease.
The ALS Association reports it has received more than $22 million in donations in recent weeks.
Bird, now president of the Indiana Pacers, challenges, among others, Indianapolis Colts owner Jim Irsay to take the ice bath.
Several current Celtics have already participated in the challenge, including Rajon Rondo, rookies Marcus Smart and James Young, as well as Celtics coach Brad Stevens.
On the group's website, president and CEO Barbara J. Newhouse said, "Without a doubt, the popularity of the Ice Bucket Challenge, the social media phenomenon that continues to sweep the nation, has encouraged tens of thousands of Americans not only to douse themselves with ice water but also to open their pocketbooks and to donate to the fight against ALS."
