Remember "planking" -- that 2011-era meme that took off on the Internet showing people lying face down in seemingly random places, a pit stop on the way to the modern, irony-infested online culture we know and love today?

These two men claim to have invented it. And their story, which is being featured in the Dutch Museum of the Image,  is just about as odd as you'd expect.

Scott Amy and Joel Marshall say they were teenagers looking for weird things to do in 1983. The pair from Edmonds, Wash., stumbled on a baseball game in Seaview Park and decided to lie down in the middle of right field. They didn't attract much attention, but when they began lying down in other places — like at weddings — people started to join in. They called the activity "face dancing."

"We just wanted to make people confused," they said.

Documentary filmmaker Bahram Sadeghi — whom you might remember as the man who prank-called the NSA — took it upon himself to track the two men down. While Amy and Marshall don't appear on the Web sites that have attempted to trace the origins of popular memes, Sadeghi says he became convinced of the pair's claims when they showed him an old yearbook photo (at 6:10 into the video below).

"Maybe they are a part of internet conspiracy of distraction and shady matters?!" Sadeghi joked in an e-mail. "After visiting them and talking to them, their friends, Scott's family and then seeing the actual park, I am convinced that they are real." Sadeghi added that "if anybody can prove the other way, they can contact me," and he would investigate.

Other potential claimants to the title of Planking Inventor include a New Zealander named Paul Carran, the Australian rugby player David Williams and the operators of a French art Web site.
