Q: What is the tallest building in the world? A: A library- it has the most stories!\nWhat do you think is the punchline of the above joke?
Explanation: The word story has more than one meaning: the floors of a building, a 5 story building for example, or an account of events that happened to real or imaginary people.
Libraries are filled with stories about people and animals and things and … so libraries are the buildings with the most stories and therefore, the tallest.
Here is a link to the tallest buildings but not necessarily the most stories- that would be a library!
