Team GB will win 27 gold medals at the Olympic Games, by far its largest haul in a century, according to an Irishman who drinks in a pub opposite the Olympic Site.
Seamus O'Derekson, 49, from Bow Road, East London, says he plucked the figure out of the air when confronted by a BBC reporter last weekend - and now the amount has been repeated around the world - in some cases wrongly attributed to a Sheffield University.
Mr O'Derekson, whose friends call him Nostril O'Seamus on account of his large hooter - tried to justify the figure last night in an exclusive with the sloof "Well, da lads ya know, could do well in da athletics. And da swimming, not da football, but maybe da other tings, ya know.
Mr O'Derekson who used to write horoscopes for the Sleaze of the World sunday tabloid - is currently unemployed, although hoping to get work during the games reading peoples palms outside Westfield Shopping Centre.
