So at this stage, the ALS Ice Bucket Challenge needs no introduction. It's all about raising money for charity. All the big US celebrities are doing it. Even Daithi got in on the act last night.
But for some people, the concept of a filling a receptacle with iced water and tipping it over their heads is a little, well, complicated.
Sometimes those people make a complete and utter balls of it, as with this guy, who made us snort our coffee all over the monitor this morning (the IT guy was NOT impressed).
And once you've started down that rabbit hole, there is literally no return - presenting an entire compilation of the best Ice Bucket Challenge #fails, ranging from the NSFW (bikini top girl) to the predictable (all those dropped buckets); from the surreal (pot stuck on head guy) to the ridiculous (our favourite - the rotteweiler at 1:24) and from the funny (most of them) to the really quite worrying (we really hope the girl at 0:43 was ok afterwards!)
Enjoy! (NSFW for language and um, other stuff)
Oh and let's not forget this poor girl...
ALS (amyotrophic lateral sclerosis) is a progressive neurodegenerative disease that impacts nerve cells in the brain and the spinal cord. It is also known as Lou Gehrig’s disease or here in Ireland as Motor Neurone Disease (MND).
The challenge was originally the idea of Massachusetts resident Pete Frates, 29, a former college athlete who has been living with ALS since 2012.
The idea is to grab a bucket of ice water and throw it over yourself, then nominate three other people to do the same thing, with the video posted to YouTube, Facebook or Instagram. Anyone who is challenged must do the same thing within 24 hours or donate $100 to the ALS Association (most people do both).
Celebrities to have taken the challenge include Bill Gates, Oprah Winfrey, Steven Spielberg, Niall Horan, Cristiano Ronaldo, Justin Timberlake, Justin Bieber, Iggy Azalea and many, many more.
