What do you know? Lots of people, including Kevin Durant, challenged LeBron James to do the ALS Association's Ice Bucket Challenge. So he did it. On a boat.
He then challenged his sons and President Obama. You have to think real highly of yourself to challenge the President of the United States of America by hitting him up with the metaphysical extension of a chain letter.
The ALS Association has now raised $10 million through the Ice Bucket Challenge. You can donate directly, with or without dousing yourself in ice water, at the Association's website.
