The ALS 'Ice Bucket Challenge' is sweeping the globe and several members of the Everton squad have already taken part. The challenge - if you have not already seen or heard - involves pouring a bucket of icy water over your head before nominating three other people to take the challenge, often giving themselves 24 hours to comply. After accepting the challenge you make a donation to an ALS charity of your choice, and failure to accept the challenge means having to make an even bigger donation!
The craze is designed to raise awareness for ALS (Amyotrophic lateral sclerosis) which is known as Motor Neurone Disease in the UK. Particpants have been donating to the ALS Association in the US or the Motor Neurone Disease Association and Macmillan Cancer Research in the UK.
Here's the Everton players and staff to have braved the bucket so far:
Romelu Lukaku nominated Didier Drogba, Kevin Mirallas and Eden Hazard after his challenge.
Ross Barkley nominated Duncan Ferguson, Huddersfield's Lee Peltier and boxer Tony Bellew.
Darron Gibson nominated Wayne Rooney, Phil Jagielka and Jonny Evans. Phil Jagielka bravely stepped up after accepting Darron Gibson's nomination, and nominated the gaffer Roberto Martinez!
Martinez's bucket looked more like a waterfall, and then passed the challenge on to Everton chairman Bill Kenwright, and Blues-bashing TV commentator Martin Tyler, who famously accused Everton of throwing the game at the end of the season against Manchester City.
Duncan Ferguson accepted Barkley's nomination - and then nominated Sky Sports News presenters Natalie Sawyer and Hayley McQueen!
Marouane Fellaini may not play for Everton anymore, but he deserves a mention because he nominated David Moyes!
Moyes took it like a sport, and in turn nominated Europe's Ryder Cup captain Paul McGinley, legendary popstar Rod Stewart and our very own Leon Osman.
Tim Cahill was one of the first to get on with the challenges, and braved it like a rock, managing to remain completely unmoved. He went on to nominate Tim Howard who has so far ignored the challenge!
Everton's Head of Medicinal Services Danny Donachie took the challenge from a completely different angle, with a yoga-inspired pose.
And if you are unlucky enough to be nominated, don't forget to donate!
