Cold Like War Puns

My Dad told this one a few months ago during a family dinner...

During the Cold War, an American ambassador and his wife were having dinner with a Russian ambassador and his wife. The meal was going well and everyone was having a good time until the American looked out the window and commented on the weather, "Looks like it is snowing outside." The Russian, named Rudolph, replied, "No, it's definitely raining." The debate went on for a few minutes and became quite heated until finally the American's wife spoke up and said, "Rudolph the Red knows rain, dear."
