This might get you started:

  (defun parrot ()
    (interactive)
    (save-excursion
      (with-current-buffer (messages-buffer)
        ;; *Messages* seems to have a newline at end
        (goto-char (- (point-max) 1))
        (message "last message was '%S'"
                 (buffer-substring-no-properties
                  (line-beginning-position)
                  (line-end-position))))))

A couple of notes:

 - it seems that messages not always end up in the *Messages* buffer
 - the function (messages-buffer) is the recommended was to retrieve
   the messages buffer, which (most of the time? always?) is called
   *Messages*
 - you might want to double check the strategy for fetching the last
   line (i.e. going to point-max - 1
 - I put the thing into a message with (buffer-substring ...), you
   might want to dump it directly into the kill ring, of course

In the meantime, Stephen's reply seems to have addressed most of the
above points, anyway; but the recommended way to access *Messages*
might still be helpful.

Cheers
