Scores of people are taking the Ice Bucket Challenge to raise awareness, and money, for the ALS Association.
Even Mirfield movie star Patrick Stewart has joined the fun, with his own classy take on the phenomenon.
But one Longwood man decided to add some superhero style to his charity efforts - dressing as Gotham legend Batman for his Ice Bucket Challenge.
John Longson, of Longwood, was nominated by his dad to take the icy plunge to raise awareness of motor neurone disease.
The 25-year-old dressed as the caped crusader at Greenhead Park, tipping a large bucket for icy water over his head.
But his challenge had a surprise ending - click below to watch the video:
John said: "I wanted to do it a bit differently, and my dad did it dressed as Donkey from Shrek."
His original plan was to jump into Greenhead Park's fountain afterwards - but the water was too shallow, so he opted for the pond.
"I tried to dive into the water afterwards but it was too shallow.
"The water in the pond was freezing - worse than the bucket to be honest!"
John has nominated the rest of his band, The Zillaz, to take the Ice Bucket Challenge - and the Examiner's own Gavin Castle.
And in case you missed it, here's a more stylish version of the Ice Bucket Challenge, as devised by Star Trek and X-Men legend Sir Patrick Stewart.

The Ice Bucket Challenge has taken social media by storm, with celebrities queuing up to tip a bucket of ice cold water over their heads in support of American charity the ALS Association.
The association supports sufferers of amyotrophic lateral sclerosis, a neurodegenerative disease, and funds research into finding a cure.
