When Brandon and Andrea are on their date, she shows him a booth called "Juanita" and asks if he wants to make a wish. Brandon says that it seems familiar, and Andrea says that it's just like the movie, "Big". But it's nothing like the movie. In "Big" the boy makes a wish on a "Zoltar" machine, and he looks evil, while this "Juanita" booth looks like a gypsy.
