Former US president George Bush takes part in the Ice Bucket Challenge and nominates Bill Clinton to do it next.
Before he gets a dunking he says: "I don't think its very presidential for me to be splashed with ice water so I'm just going to write a cheque."
His wife and former First Lady Laura Bush then pours a bucket of freezing water over his head saying: "That cheque is for me. I don't want to ruin my hairstyle."
Afterwards he challenges fellow former commander-in-chief Bill Clinton to take part.
"Yesterday it was Bill's birthday and my gift to Bill is a bucket of cold water," he joked.
