Guide to the essential differences between Americans, Canadians,
Britons, Australians and New Zealanders.
Aussies: Dislike being mistaken for Poms (Brits)

Kiwis:Happy to be mistaken for anyone.
Aussies: Believe you should look out for your mates.
Brits: Believe that you should look out for those people who belong to
your club.
Americans: Believe that people should look out for & take care
ofthemselves.
Canadians: Believe that is the government's job.
Kiwis: Believe the Aussies will look out for them.
Aussies: Are extremely patriotic to their beer.
Americans: Are flag-waving, anthem-singing, and obsessively patriotic.
Canadians: Can't agree on the words to their anthem and don't sing
anyway.
Brits: Don't sing either but have military bands to play the anthem.
Kiwis: Sing their anthem but nobody listens except when someone sings it
in Maori and everyone complains.
Americans: Spend most of their free time glued to the idiot box.
Canadians
