Jeremy Clarkson's partner Lisa makes brutal comment about their sex life

Clarkson's Farm returned to our screens last week for season four and with it came the unfiltered humour that we've come to expect from the show.

There have been plenty of questions about what fans can expect to see at Diddly Squat farm this time around, especially amid the rumours that Kaleb Cooper might have been replaced.

The 26-year-old has become a fan favourite thanks to his efforts on the show, as well as his three books which have seen his fame and fortune explode.

While there are plenty of serious topics that are also discussed on the show, such as Jeremy Clarkson's recent health concerns, for the most part it is an entertaining insight into the former Top Gear host's life on the farm.

And this was perhaps summed up best by the comments made by Lisa, and new addition Harriet Cowan, during one of the newly-dropped episodes of the show.

Harriet is introducing a new male pig to Jeremy on the farm, and pointed out the 'little clitoris' on one of the female pigs. For those of you that don't know, and are perhaps too scared to google it, the clitoris is a female sex organ which is present in mammals, ostriches and other amniotes.

However, this was clearly not something Jeremy was aware of, as he responded: "Pigs have clitorises? I didn’t know that this morning. There has been no morning in the last 63 years that I’ve known that."

Harriet then told Lisa: "He says you can’t see it [the clitoris]."

Which is when Lisa provided the brutal yet very funny remark of: "Oh, Jesus – he can’t find it either, I can tell you." Jeremy had laid it on a plate for her to tap it in, but you've got to admire her making that joke on a television show with millions of viewers.

Not wanting to hold back, she piled on the misery for Jeremy, by saying: "Do you not know what a clitoris looks like? Have you never found one? You’ve never seen one? It’s the start of the vagina, love."

Given that the pair have been dating for eight years now, you would hope that Jeremy's sexual geography is better than Lisa is letting on.

Hopefully it's better than his quizzing skills, as he left a Who Wants to Be a Millionaire contest in the mud when he struggled to answer the £1 million question which was posed to him via a helpline.

Clarkson's Farm is available to watch on Amazon Prime now.
