A pedestrian has been caught on camera moonwalking along the road in a tunnel on a busy A road in Wales.
He was one of four people seen walking through the Pen-y-Clip tunnel, near Penmaenmawr, in the early hours of the morning.
The video footage shows a group of four people walking along a pavement beside the dual carriageway, before one of the group walks into the middle of the road.
The person proceeds to perform a spin, kick the air and wander to the other side of the carriageway before bending down.
There were no cars but the tunnel has a 70mph speed limit and makes way for the A55 dual carriageway.
Traffic Wales warned that it is "not only putting yourself in danger, you're also endangering the public."
A Welsh Government spokesperson said: "This is very dangerous and should be avoided at all costs.
"Traffic officers will approach any pedestrians spotted and advise them to leave the road."
