It sounds like a sketch from a comedy show.

Two blokes build a fence - then realised they've fenced themselves in.

The only thing is, it's not a sketch, it actually happened.

What's more, the face-palming moment was captured on camera.

It's understood the amusing incident happened in the Cheetham Hill area of Manchester last week.

Two men were building a fence around a house and had parked their white van carrying their materials on the driveway outside.

They got to work, erecting several posts, and then began to put in the concrete panels.

It is at around this point that they realised their mistake.

Photos taken by Col Condron, who was working at a property nearby, show the men trying to squeeze the van through the posts.

The 40-year-old told the M.E.N: "They parked the van, built the fence, and forgot the van was there.

"It took them about half an hour to get it out. They had to take the fence apart again, and then pull the fence posts back in the wet concrete.

"They got the van out and put it all back together again."

Col shared the images on Facebook, saying, "Only gone and fenced his van in - the helmet."

So far it's had more than 800 shares.
