A Scot and an American were talking about playing golf during the various seasons of the year. "In most parts of the USA, we cannot play in the winter time. We have to wait until spring" the Yank said. "Why, in Scotland, we can even play in the winter time. Snow and cold are no object to us." said the Scot. "Well, what do you do; paint your balls black?" asked the American. "No," said the Scot. "We just put on an extra sweater or two."
