If I had to pick one year to represent the Fifties, I'd pick 1958. For one thing, it was the year that the folks at Wham-O, always looking for new ways to raise the level of American culture, gave us the Hula Hoop. This was a bright-colored plastic hoop that you spun around your hips using a hula-type motion. I realize that this sounds stupid, but you must trust me when I tell you, as one who participated extensively in this fad, that it really was stupid. In terms of intellectual content, the Hula Hoop made the Frisbee look like international championship chess.
