The Smallest Number

...is so small you can't see it. It is stored on a box so small you can't see it, which is in a drawer so small you can't see it, in a dresser so small you can't see it, in a room so small you can't see it, in a house so small you can't see it, on a street so small you can't see it, in a neighborhood so small you can't see it, in a city so small you can't see it, in a county so small you can't see it, in a country so small you can't see it, in a world so small you can't see it. The whole thing is kept in a box so small you can't see it which is also kept in a house so small you can't see it. That house is in my banana, which is why I can't eat it.
