It looks like a mobile in 1920 - so it must be time travel...
APOLOGIES for the delay - I'd like to say it's been unavoidable but it's really due to summer indolence.
But now we're back - try this one on for size....
A Belfast film-maker has posted a video on the internet showing what he says could be evidence of time travelling.
George Clarke from Belfast has been puzzled for more than a year by a scene in a film which appears to show a woman talking on a mobile phone.
The unusual thing is that the movie was made by Charlie Chaplin in 1928 - long before mobile phones were invented.
In the eight days since George posted the clip on Youtube - more than 1.5m people have viewed the video online.
Even the US talk show host Jay Leno created his own spoof version.
George was checking the extras on a Chaplin DVD box-set and began watching a clip of the 1928 Hollywood premiere of The Circus.
"As I sat back to watch it I realised in the first 30 seconds there's A lady strolling by with her hand up to her ear which looked quite familiar in today's society."
He added: "My initial reaction was that's a mobile phone, they weren't around then, my only explanation - and I'm pretty open-minded about the sci-fi element of things - it was kind of like wow that's somebody that's went back in time."
The only explanation was that someone went back in time - not that it was just someone holding something up.
