This story happened in reality, even though its likelihood is, how to say, zero: A man with red hair and beard sat down on a flight, and a few minutes later... his twin sat down next to him.
It's just that there is no biological connection between the two.
The story, which was uploaded to the social network by a friend of the wife of one of the "twins," received millions of views online.
The woman wrote: "The guy on the right is my friend's husband, and the guy on the left is a complete stranger. I can't stop looking at this, they look so alike.".
The many followers offered a variety of ideas for the new siblings - from a DNA test that would reveal a possible and strange connection between the two, to a joint coast-to-coast tour with the interesting story.
