[Willie Green]

A three-century-long cold spell that chilled Europe 8200 years ago was probably caused by the bursting of a Canadian ice dam, which released a colossal flood of glacial meltwater into the Atlantic Ocean.

I read about that in Sports Illustrated.
The dam was taken out by an errant stone hurled during that year's national curling championships.
Caused one helluva mess.
Darn socialist government banned curling and the Canucks had to play with much smaller stones called "pucks".

Prehistoric Canadian slamming his stone to the ground in disgust: "Oh, puck it!"
