I noticed when coming back to Australia that we have an entirely different sense of humor here. I suspect its a combination of "unnecessary Victorianism" blended with the American cocktail of "liberated" + "deeply stifled".
A classic for instance is this alcoholic "party drink" called popsy. We bought it on a trip to Tallin from Helsinki.
It looks rather like a sperm ... doesn't it
and incase you were uncertain of that the nice little logo reminds you
so, is it trying to get you in the mood, or is it just a warning?
Can't imagine them being popular here ... despite the fact that its popular here.
