Ghostbusters II

On the first level, the player notices three barricades blocking three of the lanes. Now, by their height, it could be supposed that they look low enough to jump over. This would not be an unreasonable guess. However, they are impossible to jump over, resulting in the loss of a life for a player trying that tactic. So then, now knowing to dodge those particular sorts of barricades rather than try to hurdle them, the player immediately comes across another interesting sight.
