The ALS Ice Bucket Challenge is a craze unlike anything seen in years. But how exactly did it morph into the sensation it is? The origins of the movement may surprise you.

Watch this heartbreaking story about how a former outfielder on the Boston College baseball team became the inspiration for the Ice Bucket Challenge, leading a charge that has seen people donate millions of dollars.

The irony of Frates contracting ALS should not be lost. Like Lou Gehrig, Frates was a gifted baseball player robbed of his prime years by this devastating disease. As you can see, though, he continues to fight, even while ALS continues to attack his body.
