A preacher, a philosopher and a scientist once took a train through Scotland. As they were traveling they passed a brown cow. The preacher said, " there are brown cows in Scotland". The philosopher said, "there is at least one brown cow in Scotland". The scientist then said, "there is at least one cow in Scotland that appears to be brown on one side".
