Staff at an insurance broker gunged the boss - and raised more than £10,000 for Comic Relief.
Workers at Adrian Flux pledged cash towards the bosses they wanted gunged.
Members of the 900-strong workforce at Adrian Flux Insurance watched 62 colleagues get completely covered in aid of the cause.
The fate of over 100 managers and supervisors was placed in the hands of staff members at the firm, which is based in East Winch, near King's Lynn.
The original goal was to raise £5,000 and gunge almost 40 bosses. But the fundraising target more than doubled - and even more managers were placed in the hotseat. It took three hours and 600 litres of gunge to get through everyone.
Donna Desborough, a PA at Adrian Flux and the event's organiser, said: 'We're very proud to have raised so much money this Red Nose Day through our 'Gunge the Manager' fundraiser.
'Everyone has had a good laugh pledging the cash and then watching the managers get gunged - the atmosphere has been fantastic.'
She added: 'I agreed to be gunged if we reached the £5,000 fundraising target. I'm now thinking: 'Why did I agree to that?' But all the cash raised is all going towards a great cause.'
Georgina Bishop, an administrative team manager at the firm, was among the managers gunged.
Afterwards, she said: 'I thought I was a good boss, so I can't believe I've actually been gunged. But my team said that I look good all the time and they wanted to see me not looking my best.
'Even though I feel horrible right now, it's all for Comic Relief and we've had a great time fundraising.'
After being gunged, Leown Bray, customer service floor manager, said: 'I only had £3 against my name for a long time, and then the amount went through the roof after saying that I didn't mind getting gunged. That one comment completely backfired on me - but it's all for a great cause.'
