When you come home from a LADs' trip to Greece, you might be carrying a terrible hangover and a scratch or two. But you don't expect to return with one of the most famous face tattoos scarred into the side of your head.
Well that's what James Colley had to deal with after a trip to the island of Zante.
He jumped at the idea of a cheap €10 henna tattoo and got the classic Mike Tyson print inked onto the left-hand side of his face. Most people would have had that temporary tattoo for just a few weeks - but unfortunately for James, this one was going to hang around for a bit longer.
His tweet has been liked by 45,000 people, some of whom have shared their own story about getting scarred from a henna tattoo.
It all has to do with what substance the tattoo artist uses for the print.
Teenager Teigan Koorts went through a similar ordeal while holidaying in Greece because she didn't know the difference between henna and black henna.
While they might sound similar, they produce very different results. Henna is a natural dye from the henna plant and will provide a temporary tattoo. But black henna is a chemical substance often found in hair dye products. When that substance interacts with the skin it can cause chemical burns and scarring that can last for months, even years.

Thirteen-year-old Teigan was eventually taken to hospital and put on strong antihistamines and a steroid cream. She was told by doctors that she could have a life-long sensitivity to normal hair dye products.
Teigan's mum Kirsty put out this message: "You see so many children on holiday, some as young as four, getting henna and not enough people know the difference. With everyone on summer holiday at the moment, I just want to warn everyone to avoid black henna."
Make sure if you're getting a henna, you know what the tattoo artist is using for ink.
