At the Foto Hut, Big Rhonda tells Fez she wants to wait to have sex. Before they leave, Fez says he has to go sit in the snow. The next scene shows the Formans' driveway. Everyone is wearing winter coats, but there's no snow. The grass and bushes are green, like springtime.
When Fez and Big Rhonda are in the Foto Hut, there are several yellow boxes on the table. Fez puts away only one of them, but when the table is shown immediately afterward, it is empty.
