I heard that the common belief in The Great White North was that the earth is flat, for it is the hat of a mountie. This hat is on the back of a giant moose which itself is up in a tree.

When asked why the moose is up in a tree, the standard response is "Where else would you expect to find the moose?"

To head off any possible questions,the tree with the moose in it isn't on anything, its just tree all the way down.

The world will end when the great lumberjack chops down the tree causing a time of earthquakes and the world hat will be crushed.
