Famous quotes containing the word yellow:
“Her little loose hands, and dropping Victorian shoulders.
And then her great weight below the waist, her vast pale belly
With a thin young yellow little paw hanging out, and straggle of a
long thin ear, like ribbon,
Like a funny trimming to the middle of her belly, thin little dangle
of an immature paw, and one thin ear.”
—D.H. (David Herbert)
