"Before retiring to bed, [Theodore] Roosevelt and his friend the naturalist William Beebe would go out and look at the skies, searching for a tiny patch of light near the constellation of Pegasus, "That is the Spiral Galaxy in Andromeda," they would chant.  "It is as large as our Milky Way.  It is one of a hundred million galaxies.  It consists of one hundred billion suns, each larger than our sun."  Then Roosevelt would turn to his companion and say, "Now I think we are small enough.  Let's go to bed."
