sport news Chris Kamara's blunder and porn noises interrupt Gary Lineker... the biggest TV ... trends now

Live sport often draws in enormous viewing figures and is one of the most lucrative opportunities for any channel to top the ratings, but it does not come without its risks - as numerous presenters have found out in recent years. 

And powerhouses like the BBC are no different, after porn noises were heard throughout their coverage of Liverpool's FA Cup clash with Wolves on Tuesday, as a result of a prank from YouTuber Daniel Jarvis. 

But that is by no means the first time broadcasters have been left red-faced by blunders live on air for their viewers to see, and here Sportsmail takes a look at 10 of the most hilarious moments in the past. 

Porn noises interrupt BBC's coverage 

Tuesday evening saw Wolves host Liverpool in an FA Cup replay, but it was not Harvey Elliott's sensational strike that drew the most attention from viewers. 

As they tuned in for the pre-match build-up to the game, fans at home will have been able to hear some very loud moaning noises coming from somewhere in the studio, with Gary Lineker and Co struggling to keep their composure.

After around 10 minutes, Lineker handed over to a smirking Alan Shearer in the commentary gantry as viewers were finally given a reprieve, although the veteran presenter clearly saw the funny side of the prank. 

He took to Twitter to share a picture of the phone that had been playing the noises, with the caption: 'Well, we found this taped to the back of the set. As sabotage goes it was quite amusing.'

Daniel Jarvis claimed responsibility for the stunt, posting a clip on Twitter of him placing the phone at the back of the BBC studio earlier in the day, as well as a video showing followers how he carried it out. 

ITV viewers miss Gerrard's World Cup goal 

Now cast your minds further back than Tuesday, to the distant days of summer 2010, when World Cup fever was once again gripping the nation ahead of England's first match of the tournament, against the USA. 

Although the game is perhaps best known for Rob Green's awful clanger that led to a 1-1 draw, ITV viewers will remember that they were unable to see Steven Gerrard's brilliant opener to the game. 

With just three minutes on the clock, Glen Johnson had the ball in his hands to take a throw-in when coverage cut to a Hyundai advert showing cars in Argentina and Brazil colours play a football match. 

But when scenes from South Africa did return, Three Lions fans were stunned to find their side were already in the lead, after a Steven Gerrard goal had put his side 1-0 up and was celebrating with his team-mates. 

Kamara misses red card 

There is no TV gaffe more famous than Chris Kamara's iconic 'I don't know Jeff' moment on Sky Sports' Soccer Saturday, which has almost become an institution in  its own right. 

Jeff Stelling was clearly better clued in than his colleague, as he sent to the on-the-spot reporter for an update of Portsmouth's clash with Blackburn at Fratton Park, asking for details on a red card that Kamara hilariously knew nothing about. 

After Stelling asked who the sending off had been for, Kamara replied: 'I don't know Jeff! I must have missed that, has there been a red card?'

With his Sky colleagues in fits of laughter Stelling continued to try and get further information out of the much-loved Kamara, but to no avail despite repeatedly asking what had happened.

'I don't know Jeff,' continued a laughing Kamara, before his presenter informed him that Anthony Vanden Borre had been sent off

But Kamara was not finished, and when Stelling jokingly asked him to count how many players where on the pitch on his fingers, he responded: 'No you're right, Jeff - I saw him go off but I just thought they were bringing a sub on!' 

And as the camera cut away from a bemused, shrugging Kamara the raucous laughter of the Soccer Saturday could still be heard, and the blunder has now become a key segment of English football lore.

Inverdale's slip of the tongue

John Inverdale's radio broadcast of the Cheltenham Festival on 5Live in 2015 drew widespread criticism after the veteran presenter used a particularly colourful turn of phrase when reflecting on the career of former jockey John Francome.

A slip of the tongue saw Inverdale left embarrassed as he spoke to Francome and racing star Lizzie Kelly, who was taking the presenter through what it takes to be a professional jockey.

'You get wet, you're mucking out, and it's hard work.

'But through all of that it's a way of life that most of them wouldn't swap, a lot of people go off and do other things and then come back to it.'

To which Inverdale replied: 'This is looking at it through rose-c***ed, rose-tinted glasses from the past... 

'I apologise there for a slip of the tongue, but Lizzie your love of the sport just shines through.'

Kelly remained professional, however, and although she struggled not to laugh she replied: 'Oh yeah, because, as I've said it's very important to love it or you wouldn't do it otherwise.' 

Despite his insistence that the blunder was down to a slip of the tongue, the British broadcasting powerhouse was faced understandably with criticism from their viewers as a result of the poor language from one of their most experienced presenters, who ultimately left 5Live in 2019.

Inverdale sparks furore with Bartoli comments

But that was not the first time Inverdale had landed himself in trouble while live on broadcast for the BBC, having once again sparked furore for his comments on then-newly crowned Wimbledon champion Marion Bartoli's looks. 

On the day of her memorable SW19 triumph in 2013, Inverdale could be heard by BBC viewers saying: 'Do you think Bartoli’s dad told her when she was little “you’re never going to be a looker?”

'"You are never going to be somebody like a [Maria] Sharapova, you're never going to be 5ft 11, you're never going to be somebody with long legs, so you have to compensate for that."

'"You are going to have to be the most dogged, determined fighter that anyone
