A train arriving in Scotland contained a party of three academic men. Looking out of the window, they saw a cow. The professor of ECONOMICS said: "Look, Scottish cows are brown." The professor of LOGIC said, "No: we can see there are cows in Scotland, of which at least one is brown." The professor of MATHEMATICS corrected them both: "My friends, we can say only that there is at least one cow in Scotland, and one side of it appears to be brown."

Thank goodness that I am an Historian and a happy SCOTTISH DANCER.
