The disease has paralyzed McClain from the shoulders down, and taken away his ability to speak. However, he still explains the disease and who he chose to pass the challenge onto through the speech synthesizer he uses to communicate.
He asked all his Facebook friends to not only "take the ice bucket plunge but I also challenge you to make a donation of what you can to the ALS association."
In true Texas fashion, he completed the challenge with Texas-shaped ice.
