Watch George W. Bush Get a Bucket of Ice Water Dumped on His Head

Bill Clinton may be next.

In the realm of great presidential debates, where every American executive is stacked up against every other on some front, there's now at least one spot where George W. Bush has exceeded Barack Obama: Ability to be doused in ice water.

On Wednesday morning, the former president posted a video on his Facebook page for the ALS Ice Bucket Challenge, the charity event that is still dominating Facebook news feeds everywhere.

Laura Bush, the former first lady, poured the water over her husband's head. And, as the challenge goes, Bush passed the ice baton to Bill Clinton.

Bush isn't by any means the first politician (or former politician) to be submerged in ice water for charity. But so far at least, Obama has said that he won't enter the fray, outside of writing a check for the ALS charity. That's despite challenges coming his way from Ethel Kennedy,LeBron James, and, uh, Justin Bieber.
