Guilty Parents was introduced with a 'square-up reel' that denounced sexual ignorance as "the black plague of adolescence". The square-up reel was a common feature of exploitation industry films. It was usually characterized by a statement from the film's producer, or an 'expert' in the relevant field, which condemned the immoral nature of the subject matter that was about to be shown. Often used as a means of 'justifying' the exhibition of the film on the grounds of its 'educational' content, the square-up reel stressed the sincerity of the filmmakers' intentions and the valuable information, which was otherwise denied to them, on topics such as sex, drugs, venereal disease or childbirth.

In reality, of course, the reel was simply a means of circumventing censors and local police, blurring the margins of legality and, perhaps, allowing members of the audience to persuade themselves that they were attending out of an earnest desire for self-improvement.
