There is a spot in Space Quest 6 where you can skip a puzzle and go to the solution immediately... If you already know what to look for. I tried that once, since it was not my first run and I remembered the last step.

At first the narrator wonders how you did that, then he assumes you've been using a walkthrough. He shames you and punishes you by slowly draining your score counter... Before reverting it and telling you not to do it again.
