Reading through John O'Mill's Puure Piffel, I found

Homer never wrote a line,
nor Buddha, Christ or Constantine,
but you - poor pen and paper clown,
you cannot wait to write it down.

O'Mill - pseudonym for Jan van der Meulen - wrote nonsense rhymes; to him the EBN owes the word "omphaloskepsis". There's no date in the book, but it seems that it was published in 1965, and this rhyme remains the same.
