Bill O’Brien

Houston Texans coach Bill O’Brien dunks ice water over his head after an NFL football training camp practice Thursday, Aug. 14, 2014, in Houston. O’Brien was challenged by a reporter to take the ALS Ice Bucket Challenge to raise money for the ALS Association. The challenge, a social media phenomenon, is part of a program launched by the ALS Association to raise money for fighting ALS, also known as Lou Gehrig’s disease. Participants challenge others on video to do it or donate money to ALS before dumping ice cold water over their heads.(AP Photo/David J. Phillip)
