The ice bucket challenge phenomenon shows no signs of abating. Far from it, the whole stepped up a gear a short while ago.
Rory McIlroy and Tiger Woods teamed up to tip water over each other.
Tiger naturally nominated one of his old muccas from the sponsors, aka Phil Knight of Nike. McIlroy, however, excelled himself by nominating none other than George W Bush. No commanders in chief have performed the challenge yet. There are only five of them currently living and neither Jimmy Carter nor Dubya's father would likely survive it at this stage.
It's not the first time Bush has had this guantlet laid down to him. The San Francisco 49ers couch Jim Harbaugh lobbed this grenade in the direction of both Bush and Barack Obama.
McIlroy also nominated Wayne Rooney for the challenge.
