They lie rigidly face-down on rooftops, postboxes, luggage racks and even in the engine of a jumbo jet.
It's the latest and perhaps the most bizarre internet phenomenon yet to sweep the globe.
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.
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.
It seems it may have been sparked by one British group of friends who grew bored with posing for the usual holiday photographs.
Newcastle doormen Scott Wood and Wayne Pyle set up a Facebook page after a trip to Majorca. Mr Wood, 34, said: 'I started doing it when I was on a lads'holiday.
He added: 'We want people to find the most random places they can - the weirder the better. 'There's so much misery around these days, with the recession and everything - this is an excuse to have a joke and do something silly.'
Fan Danielle Mitchell, 23, from Newcastle, said the so-called game had become a hit with her own circle of friends. 'We are always looking for weird places to lie down,' she said. 'I think everyone should have a go at the Lying Down Game - it's very liberating.'
