A man travelling back from a three-day stag do in Benidorm was left mortified after a woman's moans began emitting from his own suitcase.
Cudge Cullinan, 64, was left frantically rooting through his luggage to stop the X-rated noises blasting out, much to the amusement of passersby at Alicante airport.
In a hilarious video, the panicked 64-year-old can be seen rummaging through his belongings, desperately trying to find the Bluetooth speaker his son Lewis has sneakily packed.
Lewis, 30, had asked his dad whether he could just pop it in his suitcase, claiming he had no space - but in fact was planning a cheeky prank.

While waiting in the queue to check their bags in, naughty Lewis hit 'play' on an explicit video file on his phone, connecting to the speakers.
Suddenly, the sound of moaning boomed out from Cudge's case, with 30 people standing nearby by unable to contain their laughter.
Fortunately, Cudge took the prank well, given that the family regularly playing daft pranks on each other.
Lewis said: "We've all pranked each other over the last ten years. It started when we were sat on the sofa, I bought an air horn and I decided to get my dad with it.
"I've smashed a cake over his head, moved a chair away from him when he's gone to sit down in a restaurant. He loves it, we've got such a good relationship and banter.
"Dad is on edge. He knows if he does me, I'll get him back ten times worse. He done me on the dating show, Meet the Parents . He mugged me off on there".
Rail engineer Lewis has since gone on to share the funny video via social media, where it has since clocked up more than 7,000 likes, shares, and comments.
Lewis, of South Ockendon, Essex, said: "The idea just came to me on the coach [to the airport], I thought of it on the spot.
"On the coach, I asked my mate for his speaker and said I was going to put it in my dad's bag. I sent my mate the video of the noises and told him I was going to play it.
"We were in the airport and I couldn't see him anywhere. He got in the queue for check-in with about 30 people behind him and I ran over and said my speaker didn't fit in my bag and asked if I could put it in his".
He continued: "The speaker was on, I waited for him to walk forward a bit and gave my mate the thumbs up. My dad was looking around and saying 'what the hell?'.
"Everyone in the airport looked around and was in fits of laughter. Then it stopped and played again and he was more panicky and he gave it to me and I didn't know how to turn it off.
"I'm there thinking 'Jesus there's families around here'. It was getting too much in the end. It was typical Essex lads in Benidorm".
