The Eiffel Tower

Standing in Paris, Frankie called out to Juan,"What is that tower?" Juan shrugged and told him to look in a tour book. Frankie told him that he didn't have one. Juan told him that he would buy him one. After buying it they looked in it for an hour. They finally gave up after looking for it for forever. They decided to just ask someone if they knew what it was. They asked a police officer who told them it was the Eiffel Tower, one of the most famous structures in France and in the entire world.
