Famous quotes containing the words pushing the, pushing and/or envelope:
“Their beauty has thickened.
Something is pushing them
To the side of their own lives.”
—Philip Larkin (1922–1986)
“Would I if I could by pushing a button would I kill five
thousand Chinamen if I could save my brother from
anything. Well I was very fond of my brother and I
could completely imagine his suffering and I replied
that five thousand Chinamen was something I could not
imagine and so it was not interesting. One has to
remember that about imagination, that is when the
world gets dull when everybody does not know what
they can or what they cannot really imagine.”
—Gertrude Stein (1874–1946)
“Geroge Peatty: I’m gonna have it, Sherry. Hundreds of thousands, maybe a half million.
Sherry Peatty: Of course you are, darling. Did you put the right address on the envelope when you sent it to the North Pole?”
