It seems, after many years doing this,
discussion has finally reached school-boy
level! How about this one?

    cats exist
    to show
    that not everything
    has to have a function

Pretty good, ey? :)

Here is another interesting school-boy problem.
The result is 12.6 cm which seems reasonable.

;; if you are making a grid
;; out of beams
;; that are of different sizes
;; it doesn't look asymmetric
;; if you make the *holes* equally big!

(defun compute-wood-distance (total beams)
  (let*((sum-beam   (apply #'+ beams) )
        (space      (- total sum-beam))
        (num-holes  (1+ (length beams)))
        (hole-len   (/ space num-holes)) )
    (message "%.1f cm" hole-len) ))

;; (compute-wood-distance 139 '(6 7 9.5 9.5 9.5 9.5)) ;; 12.6 cm
