Famous quotes containing the words list, hot, number-one:
“Shea—they call him Scholar Jack—
Went down the list of the dead.
Officers, seamen, gunners, marines,
The crews of the gig and yawl,
The bearded man and the lad in his teens,
Carpenters, coal-passers—all.”
—Joseph I. C. Clarke (1846–1925)
“A boy not beautiful, nor good, nor clever,
A black cloud full of storms too hot for keeping,
A sword beneath his mother’s heart— yet never
Woman bewept her babe as this is weeping.”
—John Crowe Ransom (1888–1974)
“I’m your number-one fan.”
—William Goldman (b. 1931)
