Since Satya Nadella became Microsoft's third CEO in February, we've gradually learned more about him. He writes long memos, quotes poetry, and doesn't like to talk about the Nokia acquisition. But today we learned another, possibly even more important thing about Satya Nadella, and it is this: he will let you dump a huge bucket of water on his head for charity. Nadella is helping raise money to help fight amyotrophic lateral sclerosis, or ALS, and Microsoft contributed by staging a hackathon. (The result was a cool new way for people to communicate with the Surface using their eyes.)

But the real action was in the video embedded in this unfathomably long post on the corporate blog today. It shows Nadella taking what's known as the "ice bucket challenge," which the company describes as: "a social media movement wherein people post videos of themselves dumping a bucket of ice water over their heads. Once they're sopping wet with cold water, they then challenge others to either do the same or make a donation to an organization dedicated to fighting ALS, and that's just what Nadella did."

Nadella was challenged to do this on Twitter by former NFL player Steve Gleason, which just goes to show that people will do pretty much anything if you tweet at them.

The result is a GIF that we will revisit time and again. It's not quite Steve Ballmer chasing cake across the stage at CES, but then — nothing is.

Nadella, for his part, is trying to get the CEOs of Amazon and Google to follow suit. What say you, Jeff Bezos and Larry Page?
