Getting drenched in ice-cold water for charity is fully supported by Wiltshire police as this video, from the constabulary's Facebook page, shows.
The ALS ice bucket challenge has been circulating around social media and chief constable Pat Geenty is one of the latest people to support the cause.
Millions of people on social media have been pouring buckeits of water with ice over friends and family member's heads, while donating to the Amyotrophic lateral sclerosis.
The police's video shows a police van pulling up behind Mr Geenty, with the man who nominated him for the challenge - Wiltshire police and crime commissioner Angus Macpherson - stepping out and sneaking up behind him with a bucket of water.
The commissioner drenches his chief constable, knocking his police hat off in the process, and then the floodgates open.
No fewer than five more big buckets follow, with two female police staff missing their target and managing to chuck the water all over the feet of their boss.
Mr Geenty ends by nominating his senior police officers to undergo a similar fate, and said he would be donating £25 to Motor Neurone Disease charity - the British version of the American ALS good cause, which began the craze - and another £25 to COPS UK, a police charity.
