Famous quotes containing the words locked, bags and/or service:
“see the shaky future grow familiar
in the pinched, indigenous faces
of these thoroughbred mental cases,
twice my age and half my weight.
We are all old-timers,
each of us holds a locked razor.”
—Robert Lowell (1917–1977)
“I don’t go to church. Kneeling bags my nylons.”
—Billy Wilder (b. 1906)
“This was a great point gained; the archdeacon would certainly not come to morning service at Westminster Abbey, even though he were in London; and here the warden could rest quietly, and, when the time came, duly say his prayers.”
—Anthony Trollope (1815–1882)
