Scenes of joy and ecstasy were seen in the streets and villages across Ireland on Thursday as Mexico beat France 2-0.
New Manchester United striker, Javier Hernandez started the party with, as one drunken Irish reveller described, "The best goal I've ever witnessed!".
The cheers with ten minutes to go were loud enough to be heard in France as Mexico were awarded a penalty and Cuauhtemoc Blanco converted to send Irish people spilling out into the streets and forming an impromptu conga that broke the world record for the most number of people simultaneously dancing the conga.
Nobody knows quite whose idea it was, but in Cork, a Mexican wave was started, rippling across the country all the way to Sligo, before coming back again.
"It was amazing to watch," said Barney O'Blarney, adjusting his poncho and sombrero. "Even though I've got arthritis in both my knees and a crick in me back, I joined in with it."
When the game finished 2-0 to Mexico, there was a massive chorus of "Take that you Frenchies," directed across the channel.
The result leaves France with a mountain to climb if last world cup runner's up are to progress.
Alain Perrier, a Frenchman who had unwisely chosen to holiday in Galway was asked what he thought of the result, to which he responded: "Bleh," with a Gallic shrug.
