Two characters passionatly kiss towards the end. Frances and Larry have also shown signs of a "love/hate" relationship. Also, having just gotten out of the shower in one scene, Frances is, of course, wearing nothing but a bath robe (but it shows nothing, not even cleaveage). But overall, there is no real sex or nudity.
Frances' guidance counselor is invited to dinner. She tells Frances' mom that she has a "lovely little bust" and Frances' mom makes a shocked and offended face. This is an innuendo joke for older viewers; the counselor is not referring to the mom's bust size but to an anthropology bust statue in a corner of the room.
Frances' friend Jo expresses her crush on a local boy in the neighborhood, and tells Frances not to let the cat out of the bag. The boogeyman overhears this and tries to frame Frances as the one who tells other people about the crush.
High-schoolers in one-piece swimsuits dive into a pool filled with Jell-O.
In the film's intro, Frances' father is briefly seen asleep in bed with his wife. He has no shirt on, but his legs are covered by a blanket.
Frances' brother mentions that he thinks a town news reporter woman is "a hottie".
