MELBOURNE - A bizarre "lying-down game" has become the latest fad among Facebook users.

Several groups have been set up by Facebook users in honour of the game, which has led to thousands of photographs of people lying face down in progressively odder locations, including rooftops, postboxes, luggage racks, and even in the engine of a jumbo jet.

Many pictures show people lying 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.

Those participating in the game have to lie with their palms flat against their sides with the tips of their toes touching the ground.

Doormen Scott Wood and Wayne Pyle, of Newcastle, set up a Facebook page after a trip to Majorca.

"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," News.com.au quoted Wood as saying.

"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," the 34-year-old added.

According to lying-down fan Danielle Mitchell, 23, this game has become a hit among her own circle of friends.

'We are always looking for weird places to lie down. I think everyone should have a go at the lying-down game, it's very liberating," she said. (ANI)
