Little Willie wrote a book
Woman was the theme he took.
Woman was his only text.
Ain’t he cute? He’s oversexed.
Louis Untermeyer, in his 1946 A Treasury of Laughter, wrote:
The one about little Willie and his sister proved to be the most long-lived. Years later it was used as the basis for a review of the sex-ridden Nineteen Twenties when, as F. P. A. [Franklin Pierce Adams] remarked, it was “sex o’clock all over America.” This [the above Little Willie] was the terse critical parody.
