Untitled (carpet tack)

There is a man in every town,

     A man full wondrous wise;

Who jumps upon a carpet tack,

     When he at morn doth rise.

And when he’s jumped upon the tack,

     With all his might and main,

He jumps upon another tack,

     And forthwith swears again.

c. April 9, 1904
