Just out of curiosity, if non-Americans could post questions that they felt were US-biased, I think it would go a long way. Us Americans don't see any problems, but I think it'd be interesting to see where the differences come from.
From what I've gathered:
Hot Dogs
Campbell's soup

questions are biased. Any others?
Oh, and for the record, the question says "original" Campbell's soup can. Still, in my 21 years on this planet, I've only known one "classic" Campbell's soup can.
