'Horrified' Taskmaster viewers have branded a recent challenge 'the most disgusting and disturbing thing they've ever seen on TV' - and raged that Channel 4 'should have cut it from the episode'.
The 20th series of the much-loved programme, presented by Greg Davies and Alex Horne, returned to our screens earlier this month.
A number of famous faces are taking part this time, including Sanjeev Bhaskar, Ania Magliano, Maisie Adam, Reece Shearsmith and Phil Ellis.
Thursday's episode was the second episode of the series and named Cows Are Made Of Milk.
One bizarre challenge that the stars were given was identifying hidden objects behind a wall, using just one of their senses.
They read out: 'Identify Alex's things. You may only use one sense. If you choose hearing, you get five points per item.

One bizarre challenge that the stars were given was that they had to identify hidden objects behind a wall, using just one of their senses
'Smell - you get four points, taste is three points, touch is two points, sight is one point.
'The highest total score wins. You have a maximum of 10 minutes. Your time starts as soon as you have decided which sense you will be using.
'I am looking for an adjective and a noun.'
Sanjeev went for hearing, Ania went with smell, Maisie and Reece went with taste, and Phil went with touch.
This meant that Maisie and Reece had to put their tongue through a hole in a cardboard wall, and had to put a frozen sock, wet teeth and yogurt in their mouth.
Many went to X, formerly known as Twitter, were shocked that they had to do it.
'Reece and Maisie licking wet human teeth in a bowl is one of the most disgusting things I've ever seen on #Taskmaster - and that's saying something!'
'That task was the most disturbing thing I've ever seen #taskmaster.'
Many rushed to X, formerly known as Twitter, to share how disgusted they were over the task

'Just watched someone lick a bowl of human teeth. Ah yes taskmaster the silly game show #taskmaster.'
'This is so gross but Reece saying fury hole has me cackling.'
'Gross...
'My god watching Maisie and Reece doing that task was horrifying.'
'I was going to take it back but no... this is STILL the round they should have deleted.'
It comes after fans were appalled by an 'absolutely foul and unhinged' challenge that they 'didn't think could be legally broadcast' back in June.
Episode Glass Half Most hit our screens on Thursday 12 June and Alex asked the five famous faces to eat yoghurt either the most or least dignified way.
Alex said: 'Dignity, four of them chose most dignity, just the one with the least. We're going to start with the most dignity - Stevie and Jason.'
A clip of Stevie sat in a dome with smart attire and a butler was played out, followed by one of Jason pretending the mix the yoghurt in a cocktail shaker.
Meanwhile Rosie ate hers while surrounded by people 'lacked social graces' and Fatima was seen relaxing on a sofa and given plenty of compliments as she enjoyed the food.
Next up was Mathew's - and it certainly left viewers lost for words.
Alex said: 'Now for the only competitor who settled for less. Consuming his yoghurt with the least dignity. Yes it's Mat.'
In the clip, Alex could be seen waiting for Mat surrounded by a crowd of people, while a church bell rung.
Mathew was then seen walking towards him in just his boxers, got on all fours and crawled towards Alex's feet while crying.
He then started to lick the yoghurt off his shoes and said: 'Please forgive me daddy. I've got your shoes all mucky.'
