Famous quotes containing the words sour and/or gum:
“I stand on top
of our back steps and breathe the rich air—
a mother skunk with her column of kittens swills the garbage pail.
She jabs her wedge-head in a cup
of sour cream, drops her ostrich tail,
and will not scare.”
—Robert Lowell (1917–1977)
“The hunchback on the corner, with gum and shoelaces,
Has his own wisdom and pleasures,”
—Robert Penn Warren (1905–1989)
