When they 1 the train at Heuston Station in Dublin, the Scotsman looked around and said, “Why 2 so many clocks? What a waste of money!” The Englishman didn't know the answer. When he looked at the clocks more closely, he saw that all the clocks 3 different times. “What's the good of having so many clocks,” he said, “if they all tell different times?” The Irish porter who 4 near them, heard this and shouted angrily, “What's the good of having so many nice clocks if they all tell the same time?”
