A cringe-inducing video shows a mother shoving a back scratcher down her throat, in a bizarre party trick in front of her family on Boxing Day.

In the video, captured at a home in London, the mother shows off the unusual ability while being egged on by other family members and filmed by her daughter. 

As she begins the party piece, a male voice can be hear saying: 'Go! Just don't get it wrong'.

The implement slides further into her mouth, and the woman can be heard making a strange squealing sound.

'Why are you screwing your face up?' a male voice can be heard to say.  

'What a proud moment', the daughter can be heard sarcastically saying as her mother slides the object into her mouth and down her throat. 

After the woman completes her performance, she burst into laughter, and a female voice yells: 'That's the funniest thing I've ever seen'.
