Bizarre indeed!

Yes.  The answer is _always_ yes in Emacs.  :-)

How about something like this (not tested):

(defun jo-funny-font ()
  (font-lock-mode -1)
;; The next line is taken from lisp-mode-variables in lisp-mode.el
  (setq font-lock-defaults
        '((lisp-font-lock-keywords
           lisp-font-lock-keywords-1 lisp-font-lock-keywords-2)
          nil nil (("+-*/.<>=!?$%_&~^:" . "w")) beginning-of-defun
          (font-lock-mark-block-function . mark-defun)))
  (font-lock-mode 1))
(add-hook 'c-mode-hook 'jo-funny-font)

But why do you want to do this?
