Famous quotes containing the word doubling:

    My only objection to the arrangements there is the two-in-a-bed system. It is bad.... But let your words and conduct be perfectly pure—such as your mother might know without bringing a blush to your cheek.... If not already mentioned, do not tell your mother of the doubling in bed.
    Rutherford Birchard Hayes (1822–1893)
