Peter recalls the secret level of the video game 'Donkey Kong' in which the princess is murdered and Mario helps Donkey Kong cover it up. The two come up with a cover story, suggesting they tell people they were at the movies, watching 'Ordinary People'. Donkey Kong suggests that they say they were watching 'Stripes' instead, because they've actually seen that film, whereas neither have seen 'Ordinary People'.
