Nothing graphic, overall pretty mild. Some lines of innuendo and some "silly" situations:
As a scam, a woman accuses a man of getting her pregnant, they demand he drop his pants and prove his ass isn't covered with freckles
Old woman says only way she can pay bill is with her body (comedic)
Old man comments on not being able to get it up
Man accuses wife of "screwing around" and makes a weird (non-lewd) hand gesture.
Man spanks his wife comically against his will.
Man fights in boxers after pants are torn off
Mild sexist humor between old man and old wife
