Bush in ice bucket challenge

In what could well be our favourite ALS ice bucket challenge video so far, George W Bush has gamely been drenched in freezing water for charity.

Perhaps he had run out of paint for those nude self-portraits he so loves to create and needed another diversion, but regardless the video results are pretty spectacular.

Nominated by his daughter, NBC news correspondent Jenna Bush Hager, and golfer Rory McIlroy, the former President first declines the offer and begins writing out a cheque for charity.

"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," he says in the film, before his wife, Lauren Bush, gleefully ‘surprises’ him by empting a bucket of ice water over his head.

"That cheque is for me," she says, in an unnervingly sinister tone. "I don’t want to ruin my hairstyle".
