With Harlem Shakes, flashmobs and planking you may think bizarre stunts in public shared across social media are a relatively new phenomenon - but Perth's 'limp fallers' say their craze has has been going for more than 50 years.
It might not be easy to work out when and where the modern day planking craze first began, but people attending a reunion in Perth next month to celebrate the "planking-of-the-1950s" are pretty sure they can pinpoint exactly where their art form started.
Limp falling, the art of falling to the ground almost unannounced in a public area, swept across many parts of the world in the 1950s and 60s.
It began in what was the Palace Hotel in the city's CBD according to limp faller Hugh Edwards.
Mr Edwards, who is now almost 79, said the practice was inspired by an accident at a house party of mostly journalists.
One of them fell somehow managed to fall through an asbestos wall and the image of him falling made people laugh.
"It was regarded with some amusement by those present, thus beginning limp falling," Mr Edwards said.
Those working within Perth's media began limp falling, especially while drinking at their regular, the Palace Hotel, to the bemusement of others around them.
"One person would say 'fall' and we'd all carefully put down our drinks so they didn't spill, then they'd go limp and drop to the ground," Mr Edwards said.
More people caught onto the idea of limp falling and began taking part.
As those involved, spread across the globe, so did the art of limp falling.
The practise caught on and began occurring in various places including a cross walk on St Georges Terrace and as far away as Buckingham Palace.
Mr Edwards said while he had not done any limp falling in recent years, he may do so for old times' sake when the limp fallers reunite.
"I'm 80 this year, so maybe just gently," he said.
Mr Edwards said while he wasn't exactly sure what planking was, it was probably a bit duller than limp falling.
"It looks a bit boring, just laying down," he said.
Original limp fallers and limp falling enthusiasts will reunite at an invite only event on March 15.
The son of original limp faller and Daily News cartoonist the late Paul Rigby will be installed as the new world president of the Limp Falling Association, a group which has been in hiatus for some time now.
