Famous quotes containing the words busy, beaver and/or proof:

    I have known a number of Don Juans who were good studs and who cavorted between the sheets without a psychiatrist to guide them. But most of the busy love-makers I knew were looking for masculinity rather than practicing it. They were fellows of dubious lust.

    This ferry was as busy as a beaver dam, and all the world seemed anxious to get across the Merrimack River at this particular point, waiting to get set over,—children with their two cents done up in paper, jail-birds broke lose and constable with warrant, travelers from distant lands to distant lands, men and women to whom the Merrimack River was a bar.
    Henry David Thoreau (1817–1862)

    Right and proof are two crutches for everything bent and crooked that limps along.
    Franz Grillparzer (1791–1872)
