I blame my mother for my poor sex life. All she told me was ’the man goes on top and the woman underneath.’ For three years my husband and I slept in bunk beds.

This joke uses Rivers’s trademark confessional, taboo-busting persona to satirize sexual ignorance and prudish sex education. By blaming her mother’s minimal instruction—reduced to a simplistic “top/bottom” description—she sets up a literal-minded misunderstanding that culminates in the absurd image of a married couple sleeping in bunk beds. The humor hinges on incongruity and exaggeration, but it also gestures at a broader cultural critique: how euphemism and silence around sex can produce confusion, shame, and comic miscommunication. Rivers turns private embarrassment into public comedy, using shock and self-deprecation to puncture social decorum.
