Famous quotes containing the words minutes and/or arc:
“A favorite of outdoor alcoholics, connoisseurs and Fundamentalists, these pills turn water into wine. In 10 minutes the most fetid swamp scum in the forest can become modest red, elusive and light on first taste, yet playful—one might say a trifle impudent—on the afterbite. Saves pack space by eliminating need for bulky corkscrew, decanter and bottles. Store pills on their sides in a cool dark place.”
—Alfred Gingold, U.S. humorist. Items From Our Catalogue, “Wine Pills,” Avon Books (1982)
“Male urination really is a kind of accomplishment, an arc of transcendance. A woman merely waters the ground she stands on.”
—Camille Paglia (b. 1947)
