Famous quotes containing the words ground and/or glass:

    All I’m telling you is that that little creature in there has as much right to live as you do. Don’t forget, you invaded his world. You sank a pipe six miles into the ground and when he climbed up you set dogs on him, shot him.
    Richard Fielding, and Lee Sholem. Superman (George Reeves)

    We are little airy creatures,
    All of different voice and features:
    One of us in glass is set,
    One of us you’ll find in jet,
    T’other you may see in tin,
    And the fourth a box within;
    If the fifth you should pursue,
    It can never fly from you.
    Jonathan Swift (1667–1745)
