Cato Berntsen Larsen had eagerly climbed feet-first into the public loo in Drammen, near Oslo, after volunteering to retrieve a friend’s phone.
However, the 20-year-old couldn’t get back out again.
The toilet tank isn’t connected to the sewer system, but is an old-fashioned outhouse-style loo that is only emptied once a season.
‘It was damn disgusting,’ he told Norwegian paper VG. ‘The worst I have experienced. There were animals down there too.’
And to make things even worse, Cato added to the pool of waste by vomiting almost immediately after getting into the tank.
He ended up having to spend around an hour standing thigh-deep in waste.
It all started when his friend dropped his phone down the toilet while urinating, and shouted for Cato’s help getting it back.
Firefighters had to completely destroy the toilet to get him out. It is now out of service.
