It's the latest bizarre internet phenomenon 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.

No location is out of bounds, with people lying on roofs, in the middle of roads, 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 have to lie with their palms flat against their sides with the tips of their toes touching the ground.
It may have been sparked by a British group of friends who got bored with posing for the usual holiday photographs.
Doormen Scott Wood and Wayne Pyle, of Newcastle, set up a Facebook page after a trip to Majorca.
Wood, 34, said: "I started doing it when I was on a lads' holiday in Magaluf.
"I thought that lying on the floor would be a funnier way to pose for my holiday snaps than the usual poses."
"We want people to find the most random places they possibly 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."
Lying-down fan Danielle Mitchell, 23, said the so-called game had become a hit among 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."
