CEOs Pour One Out for the Ice Bucket Challenge

YouTube/AmazonAmazon CEO Jeff Bezos takes the ALS Ice Bucket Challenge.

If you haven't heard of the ALS Ice Bucket Challenge by now, you must be living under a rock...or maybe a bucket. Celebrities, athletes, and politicians across the country have been dumping cold water on their heads to raise awareness of Lou Gherig's disease, each nominating three of their peers to tip the bucket within 24 hours or else donate to an ALS charity (most of them do both). Since it was popularized by golfer Chris Kennedy in July, the challenge has gone beyond-viral, with over $13.3 million raised as of August 17."We have never seen anything like this in the history of the disease," said Barbara Newhouse, President and CEO of The ALS Association. "We couldn't be more thrilled with the level of compassion, generosity and sense of humor that people are exhibiting as they take part in this impactful viral initiative."

Like Hollywood, the business world has taken heartily to the charitable trend--particularly Silicon Valley, as numerous tech luminaries opt to dump 'n donate. But Bill Gates, Mark Zuckerberg, and others are hardly alone in their participation; even Oprah got in on the action. Want to see? We've rounded up some of the highlights below. Take a look:
