For marriage to be a success, every woman and every man should have her and his own bathroom. The end.

Delivered as a punchline, the remark treats domestic space as a practical foundation for marital harmony. By insisting on “her and his own bathroom,” Zeta‑Jones humorously reframes “successful marriage” not as lofty romance but as everyday logistics: privacy, autonomy, and reduced friction over routines. The emphatic “The end” mimics a definitive moral to a story, suggesting the advice is self-evident and nonnegotiable. Beneath the joke is a modern, egalitarian premise—each partner benefits from personal boundaries and a small zone of control—implying that respect for individual needs can be as important as shared intimacy.
