“Bad Hair Day?” That was the question accompanying a a poster put out by London’s M&M Hair Academy…right underneath a photo of Kim Jong Un.

“We put up posters for an offer for men’s hair cuts through the month of April. Obviously, in the current news, there has been this story that North Korean men are only allowed one haircut,” said 26-year old barber Karim Nabbach, who came up with the idea, to the BBC.

M&M most certainly had some fun with the advertisement, which offered 15% discounted haircuts at the expense of the North Korean dictator. But what they probably weren’t counting on was a visit from the North Korean embassy, which just happens to be located about 10 minutes from the M&M Hair Academy. The manager kindly asked the embassy officials to leave before things got out of hand.

According to Nabbach, the manager said, “Listen, this isn’t North Korea. This is England–we live in a democracy. So I’m afraid you’re going to have to get out of my salon.”

So all’s well that ends well. Though things probably would have ended with some jail time if this was North Korea.

“We have never had to perform that haircut on anyone,” Nabbach said to The Guardian. “Perhaps if David Beckham wore it. But I don’t really see it catching on, to be honest.”
