A new dad got revenge on a pest who was sexting his girlfriend's Facebook account by replying with a picture of HIM in her frilly yellow knickers.
Now that, is brilliant!
Karl Hughes, 28, intervened after another man started sending suggestive messages to his partner Jessica Davidson - with hilarious consequences.
So when Karl - posing as Jessica - offered the creep 'sexy underwear' photos, he donned a pair of Jessica's yellow size 12 French knickers and replied with the caption: 'There ya go darling'.
Mum-of-one Jessica, who gave birth to daughter Valencia just three weeks ago, said the man had sent her unsolicited messages after spotting her out shopping.
Karl, from Middlesbrough, North Yorkshire, said: "This guy started messaging her after he'd seen us in town together with our new baby, which is a bit weird because we were clearly together.
"We were sat in bed together and Jessica had drifted off to sleep and I could see these messages coming through so I thought I'd get my own back.
"He was taking quite a creepy tone and saying things like 'I'd literally ruin you' even though Jessica had already told him we were together.
"So I thought I'd play a bit of a prank and squeezed into a pair of her pants to get a selfie and see how he liked that.
"I'm 16.5 stone and covered in tattoos so it probably wasn't what he was hoping for. It took a lot of effort to squeeze into them.
"This guy does know Jessica but they've not spoken in years and for him to start sending her dodgy messages when he's just seen us in town together is a bit off."
"He came on saying things like 'why are you so ignorant' which was a bit strange and then he started with the suggestive comments.
"Jessica says it's happened to her before so I thought this time I would teach him not to message a woman who's just had a baby.
"He was expecting a picture of her so I'm sure his face dropped when he saw me."
Karl said he had to rummage through Jessica's underwear drawer to find an item that fit him before finally settling on the saucy La Senza number.
His topless picture was met with silence, with Karl believing the recipient was too embarrassed to even send a response.
Jessica, 21, said: "The first few pairs he looked at were a bit small and everything would have been hanging out of them.
"The yellow ones have a bit of a tear on them now so I'm not sure I'll be wearing those again."
"At first I was sleeping so I didn't really know what Karl was doing but when I saw it I thought it was hilarious.
"It was pretty tragic for the other fella who obviously thinks I'm a bit of a mug if I'm going to send him sexy pictures when I've just had a baby with Karl.
"He's not replied. Maybe he's still upset. It makes me laugh at the shock he must have got after getting himself all excited. I'm not that sort of girl.
"If I see him in town again I'll just have to ask him what he thought."
That's a conversation we'd love to listen in on!
