Bush Gets Soaked But Who Does He Nominate?

George W Bush has completed the ice bucket challenge after being drenched by his wife.

The former US president had been nominated by his daughter Jenna, who works for NBC.

He appears to decline at first, saying: "I do not think it's presidential for me to be splashed with ice water, so I'm simply going to write you a cheque."

But then the former First Lady empties the bucket of ice water over his head, saying she'll sign the check instead.

"I don't want to ruin my hairstyle," she quips.

Mr Bush then challenges his presidential predecessor, Bill Clinton.

"Yesterday was Bill's birthday, so my gift to Bill is a bucket of cold water," Mr Bush said.

Mr Clinton turned 68 on August 19.

The challenge, which has involved celebrities worldwide, is to raise awareness for ALS, also known as Lou Gherig's disease, or motor neurone disease.
