Famous quotes containing the word shoe:
“There was an old woman and she lived in a shoe,
She had so many children, she didnt know what to do.
She crummd em some porridge without any bread
And she borrowed a beetle, and she knocked em all on the head.
Then out went the old woman to bespeak em a coffin
And when she came back she found em all a-loffing.”
—Mother Goose (fl. 17th18th century. There was an old woman who lived in a shoe (l. 16)
