It's often said that conspiracies are a fun way to keep our minds of the real issues in the world. Well here's a good one...
An internet sensation has been caused by a 1928 Charlie Chaplin film which allegedly shows a woman walking down a street in the 1920s while talking on a mobile phone.
The woman can be seen carrying and apparently talking into the device before entering a cinema to watch the premiere of Chaplin's then newly-released film, The Circus.
Naturally, the footage has stirred much internet debate. Is it a time traveller, or part of a time travel conspiracy? Did mobile phone technology exist in the 1920s, which the government then covered up?
Or, to paraphrase one YouTube poster, is it just a crazy old woman talking into a slipper?
Some people have even suggested that Chaplin himself is otherworldly and came to Earth to show us the future. The internet really does attract all sorts...
Despite the efforts of a young movie fan named George Clarke, who's apparently spent a year of his life trying to make sense of the footage, the mystery remains unsolved.

Naturally, Clarke has come to the conclusion that the video is "irrefutable proof" that time travel is possible. Above, you can watch zoomed-in footage of the woman and decide for yourself.
What's more, this isn't the first time that a Chaplin video has caused excitement....
Last year, an eBay buyer was shocked to discovered that his purchase, a battered container with an "old film" inside, contained a lost Charlie Chaplin film.
The film inside his £3.30 ($5) purchase was titled Charlie Chaplin in Zepped - an unseen movie starring the early cinema legend.
The buyer, Morace Park, could find no mention of the film on the Internet. So he teamed up with his neighbour, a former head of education at the British Board of Film Classification, to unravel its mystery.
Following analysis by film and Chaplin experts, was later valued at an incredible £40,000 ($64,000).
