The film has a few incidences with scantily dressed women. There is a scene in with a prostitute, no nudity is shown at all, she only appears at a door in a nurse costume for 10 seconds, and the door gets slammed on her.
A teenager announces to a home intruder that she has a "scorching case of herpes".
A teen tells another teen to "blow" himself.
Brief non-sexual nudity, showing both boobs in their entirety, though it's just a drawing Ferris makes on his computer.
A drawing of a nude woman is seen on a computer screen. Both breasts are shown but this is only for a few seconds and it is really easy to miss.
Some sex references throughout the film.
In a few parts of the film, there can be seen a small picture of a woman's bare chest on Ferris' dresser drawer. It's really blurred out though, and it's in the background.
A man and woman start kissing heavily.
A girl teenager asks a guy teenager if he saw her changing into her swimsuit. He says he did, meaning he saw her totally naked, but she says she isn't embarrassed (though we don't see anything).
A teenager poses as his girlfriend's father in order to sneak her out of school. In view of the principal, they kiss passionately; the principal only responds "so that's how it is in their family."
A Nurse-O-Gram calls at a house and, when the door is answered, sings, "I've come to restore your pluck because I'm the nurse who likes to f---" before the door slams shut.
At one point Ferris says of Cameron, "He'll marry the first chick he lays..."
