A letter from E.B. White to J.G. Case, March 30, 1962:

Dear Jack:

The next grammar book I bring out I want to tell how to end a sentence with five prepositions. A father of a little boy goes upstairs after supper to read to his son, but he brings the wrong book. The boy says, ‘What did you bring that book that I don’t want to be read to out of up for?’

And how are YOU?

Yrs,

Andy

See Over and Out.
