Bush takes ice bucket challenge . Bush has joined a growing list of celebrities across the world to take the ice bucket challenge. He did it to help raise money for Lou Gehrig's disease and chose his predecessor Bill Clinton to do it next. In a video posted on Wednesday on Bush's Facebook page, the former president, wearing a navy blue coat while sitting at a table, said he was challenged by his daughter Jenna Bush Hager to take the challenge. As he wrote the check, Laura Bush appeared with a white bucket and poured ice water over her husband's head and then said, "That check is for me. I don't want to ruin my hairstyle." Bush then announced his choice. "Now it's my right to challenge my friend Bill Clinton to the ALS Challenge," he said. "Yesterday was Bill's birthday and my gift to him is a bucket of cold water." The online campaign challenges people to either dump a bucket of ice water over their heads or donate to support research for Lou Gehrig's disease. When a person accepts the ice bucket challenge, he or she must challenge another person to partake in the raising money effort. Many famous people in different fields around the world took part in the activity, including Bill Gates, Stephen King, Christiano Ronaldo, and Lady Gaga, and so on.
