Moscow Fair on July 24, 1959 during a tour of a model kitchen, put together as an example of the typical American home by The State Department.
It quickly dissolved into a shouting match over who had the better advances in technology, even down to kitchen appliances.
It all pointed out how volatile our relationship was with the Soviet Union - how we could agree on literally nothing, and how adamant each side was portraying each other as backward and neanderthal.
Still, it made for good copy and every newspaper and magazine in the world had pictures of Nixon and Khruschev flailing arms around - all for the sake of a washer/dryer combination.
Typical of their exchange:
Nixon: "You won't conceded anything, will you?"
Kruschev: "We too, as you know, don't kill flies with our nostrils!"
Back when the Cold War became just a little bit funny.
