You'd be forgiven for thinking that the world's most successful chefs would be far too busy to concern themselves with chucking iced water over their heads.
And yet, despite punishing hours and meticulous mise-en-place, chefs across the land have managed to squeeze the ALS Ice Bucket Challenge into their day and post it online for all to see.
For anyone who's been living under a rock, this is the latest fundraising craze in aid of previously little-known American charity the ALS Association, which helps support research to combat amyotrophic lateral sclerosis (or ALS), which is a potentially devastating degenerative condition affecting the brain and the spinal cord, for which there is no known cure. In the UK, it is known as motor neurone disease.
What began as a small choice between donating $100 (£63), or taking the forfeit of having iced water poured over you and donating $10 (£6), has spiralled into a global social media craze, in which celebrities and non-celebrities partake alike, with everyone now simply donating as much as they want, via the online form here.
The total raised for the ALS Association so far has reached over $88m (£53m) and counting, with the number of donations estimated at a - quite literally â' cool 1.9m.
Other famous faces to take part include actor Benedict Cumberbatch, rugby player Ben Foden, footballers Cristiano Ronaldo and Steven Gerrard, Microsoft founder Bill Gates, singer Lady Gaga, filmmaker Steven Spielberg, Facebook creator Mark Zuckerburg, and even former President of the United States, George W. Bush (while current President Barack Obama reportedly declined the challenge, but donated anyway).
And it seems even chefs aren't immune. Here's five of the best to have swapped chef whites for water, bringing a whole new meaning to the phrase "if you can't stand the heat, get out of the kitchen"â¦
