At the beginning of the movie John Cusack is trying to get Daphnie Zuniga to tutor him. It is winter and snowing outside. She is in an indoor pool doing laps and he is walking along the outside of water. Near the end of her first lap in the pool, if you look at the upper right corner of the screen, you can see a bunch of palm trees in the sun outside.
In their dorm room, Gib's roommate asks him how zucchini is spelled, to which Gib authoritatively replies "Z-U-C-H-I-N-I". Of course, zucchini has two Cs, not one.
