It began, as these things sometimes do, while people were out spreading moose estrogen on trees
Illustrating the difference between the two countries are the most common jobs in each:
Canada – (1) moose estrogen spreader (2) pelt trader (3) dog sled mechanic (4) Zamboni driver
USA – (1) firearms dealer (2) drug dealer (3) porch pirate (4) fast food clerk

I thought there would be a comment about our Canadian ‘thing’ for hairy beaver.
