It's the latest and perhaps the most bizarre internet phenomenon yet to sweep the globe. They lie rigidly face-down on rooftops, postboxes, luggage racks and even in the engine of a jumbo jet.

Several Facebook groups set up in honour of 'the Lying Down Game' display thousands of photographs of people lying face-down in progressively odder locations.

It seems no location is out of bounds, with people lying down roofs, in the middle of the road, in front of tanks, across bars in pubs and on table football games.

The game, invented by Gary Clarkson, is intended to confuse people by lying down on public places.

Technically, the palms of your hands must be flat against your side and the tips of your toes pointing at the ground. Just as if you were standing, but vertically challenged.

Participants are told there are two aims to the challenge; that the lying down should be as public as possible and that as many people as possible should be involved.

Players are told they must have their palms flat against their sides with the tips of their toes touching the ground.
