Doubling Function

Famous quotes containing the words doubling and/or function:

“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)

“The function of muscle is to pull and not to push, except in the case of the genitals and the tongue.”
