There was drama on an unprecedented scale at Super Bowl XLIII in Tampa this afternoon, when the game between the Pittsburgh Steelers and the unfancied Arizona Cardinals, was called off at halftime due to too much grinning.
The Steelers fans were in ecstasy by the half with their team leading 17-3, but even the Cardinals followers were jovial and enjoying their day out in the sunny Florida sunshine.
The TV presenters, officials, players themselves and various other token workers around the stadium also had smiles all over their faces, as well as millions of neutral fans watching the game at home on television.
The game was all set for a dramatic second-half.
But, to everyone's astonishment, an announcement was made over the public address system that, due to overuse of the grin, the match would be abandoned and considered a draw.
As is customary in American sport, nobody understood this, and there was mass confusion, then anger. Sporadic fighting broke out, and there was less grinning than has been seen at an American sporting event for more than 100 years.
Police moved in to quell the trouble, and made 7 arrests. Three people were taken to hospital, but were later released with grins on their faces.
One spectator who had travelled to the match from Britain, told reporters:
"There was some trouble with the sickening, pathetic, overblown grins that Americans always seem to have on their stupid faces."
