That was a bit *too* quick and dirty, this works better:

(defun comment-and-dup ()
  "duplicate line at point, and comment the current one"
    (forward-line 1)
    (let ((str (buffer-substring (region-beginning) (region-end))))
      (comment-region (region-beginning) (region-end))
      (insert-string str)))

Best wishes,
