Back in February, the BBC News website published a story about a Sudanese man who had been obliged to "marry" a goat after being discovered having what can probably best be described as improper relations with the beast.
This undeniably quirky tale was confirmed for us by the editor of a local newspaper which had carried the report. The editor is a trusted BBC stringer.
The story attracted much interest and amusement at the time, but was soon consigned to the archive.
However, last week there were some bizarre developments. That goat report was consistently showing up in our "live stats" box as the most widely e-mailed story on the site.
The story was even picked up (as if new) by the soaraway Sun.
It had not been re-published, re-written or revised. So how is it that upwards of 100,000 people a day were passing it on to their friends and acquaintances?
Or could it be that some crazed animal lover has been repeatedly hitting the site with fake requests?
We put our senior software engineer Gareth Owen on the case. His verdict is unequivocal. The demand was genuine.
During a single morning, the goat story was e-mailed by readers in Australia, France, Sweden, the US, Luxembourg, India, Malaysia, Tanzania, Estonia and many other countries.
Do a search on Google for "goat and marry" – and the story is everywhere. It even gets a mention in Wedding Ideas magazine.
It seems to be a fine example of the viral nature of the web. A story is picked up and passed on to an ever growing circle of readers – a sort of chain letter in cyberspace.
Only now are there signs that the interest may be abating. For the moment at least, the story is no longer registering as one of the most popular on the website.
But the experience has inevitably raised questions about whether we should do a follow up. Should we perhaps find out if the relationship is still flourishing? And what about the kids?
