(Here I speak from the point of view of a South American. Other countries and other obsessions may skew slightly your perception of this review.)
Foreigners may notice the unusual obsession Americans have with nipples. What is merely a feeding duct in most of the Communist world and some primitive collonies is one of life's great questions in the USA, perhaps only surpassed by paint chips. In no other country, will you be reminded so constantly of the fact nipples get erect in cold weather, can poke through superheroes' steel costumes, are frequently chased by horny teenagers and so many other lifesaving subjects.
Of course, we here slave over buttocks, so what can I say.
