When the billionaire founder and CEO of Facebook is dared to throw a bucket of ice and water over his head for charity, he doesn't shy away from the challenge!
The business entrepreneur takes up the mantel after he's voted to do the task by an American politician.
After accepting the ALS Ice Bucket Challenge, Zuckerberg nominates Bill Gates, his partner at Facebook Sheryl Sandberg and Netflix founder and CEO Reed Hastings.
The three have 24 hours to complete the challenge or they must donate $100 to the ALS foundation. (They can always do both!)
We hope Bill accepts the challenge!
