I'm a Celebrity... Get Me Out of Here! campmates have a rough old time.
Since the show moved from the Australian jungle to a Welsh castle, they have had to battle the freezing cold and contend with a rumoured ghost.
They have to stay up until 4am every night for their dinner - not that they are aware of the exact time, because their watches and phones are taken away.
The celebs, who include Frankie Bridge, Richard Madeley, Naughty Boy and Dame Arlene Phillips this year, are half-starved even when they win all the available food.
Not only that, but their every move is filmed and broadcast to the public by cameras, some of which they can see, and some they are totally unaware of.
And these cameras gave former I'm a Celeb star Victoria Derbyshire the shock of her life, as she and her fellow campmates on the 2020 series had presumed they were unmanned.
That is, until they heard someone within the walls sneeze.

Writing in The Mirror, Victoria explained: "Initially we were aware of the automated cameras high up in the sleeping quarters and bathroom (not the loo), because we could hear them turning to focus on a particular campmate or conversation.
"And hidden behind the walls of the living quarters, there are actually cameramen and women, which we only realised when we heard one of them sneeze.
"But after 24-48 hours you really do forget about them. I felt slightly out of control in the first few days."
They might have forgotten about the cameras for the most part - but they would be reminded when they wanted to have a private conversation that wouldn't be broadcast.
But Victoria's campmate Shane Ritchie had a genius trick to ensure nothing was aired that they didn't want out there.
"If we ever wanted to talk about something privately that we didn’t want to appear on television, Shane told us to sing a famous song in the middle of it because ITV wouldn’t want to pay for the rights to the track, so wouldn’t include it on the show," she wrote.
Jordan North, who was a runner up on the series, has previously corroborated this and explained they sang Queen, Beatles and Disney songs because of their strict copyright rules.
"Before we went in, we were told not to sing any songs by Queen, The Beatles or Disney because we can't get them cleared," he said.
"That means you've got to get the rights for it. So if we were having a conversation that we didn't want to go on air, we'd have a conversation and we'd get someone in the background to sing 'I Want To Break Free'.
"So I'd be there with Shane Richie going, 'Is he really like that? I've always loved him on the telly'.
"Shane's saying, 'Can't stand him mate, he is nothing like you see...'
"Then you've got Vernon in the background going, 'Hey Jude, don't let me down'.
"Then we'd know it wouldn't go on air!"
Discussing the unusual cuisine offered up to the campmates when they win enough stars, Victoria said: "I’d never before eaten, let alone prepared, eel, pigeon or squirrel – but that’s what we got and we had to at least try it, otherwise it was rice and beans again or hunger pangs.
"Often the men in our camp – Vernon Kay, AJ Pritchard, Mo Farah and Russell Watson – still had cravings after we’d eaten."
And the mealtimes were utterly bizarre as food is not served until the early hours.
"Because it’s filmed in the UK again this year, unlike in Australia, every night is a very, very late night – we didn’t get to bed until three, sometimes four in the morning (obviously we didn’t have watches or phones so those times are estimates)," she explained.
"This is because the trial takes place after Ant and Dec have come into the castle, live, to announce who the public has voted for.
"That individual then goes off to do the challenge and often doesn’t arrive back until midnight - 1 o'clock in the morning.
"The food gets delivered sometime after that – which we then had to chop/wash/work out how to cook, before eating at 2.30am-3am."
She also revealed that the late night means they end up eating their breakfast at lunchtime.
"What I learned though from the whole experience is that when the pressure’s on to win stars in order to feed your fellow campmates, you can make yourself do almost anything," said Victoria.
"The food: there’s never enough of it.
"For breakfast (which we ate at lunchtime) we had a small portion of rice and beans; for tea we had the same, and then in the early hours of the morning we’d cook whatever had been won in the trial."
