The 'Ice Bucket Challenge' has become a viral sensation benefiting ALS.

Local 2's Randy McIlvoy, Britta Merwin, and Courtney Zavala took on the challenge recently. Tuesday, H-E-B's President Scott McClelland took the Ice Bucket Challenge and called out Local 2's Ruben Galvan.

Today, President George Bush jumped on board with the help of former First Lady Laura Bush.

In his video, the President stated, "I do not think it's presidential for me to be splashed with ice water. So, I'm simply going to write you a check."

As he writes the check, his wife soaks him with ice water and says, "That check is from me. I didn't want to ruin my hairstyle."

Who will he challenge in return? Well, his good friend President Bill Clinton of course! He says, "Yesterday, was Bill's birthday and my gift to him is a bucket of cold water."
