Zsuzsa Czinkóczi (8) is nude for the first half-hour of the movie, except for one brief moment when she trades "clothes" with her little sister. Now Zsuzsa is wearing a potato sack and the 6-year-old Rózsi is nude (except for a melon helmet Zsuzsa was playing with.)
Soon thereafter he nicks a book on human anatomy, and that evening while in the bathroom, measures the size his own genitals to the pictures in the book.
