If you know anyone from another geographic area, a good way to get in their good books is to say "Hey! Why don't you go back to XXXXXX!" when they do something wrong.
Like, say someone from Manitoba cuts you off... yell out your window "Hey, why don't you go back to Manitoba!"
This shows how caring and understanding of other cultures you are, I mean, afterall, you're willing to send them an invitation to their place of origin!
