Alessandra Stanley wrote in today’s Times a review on the reality series “Gigolos”.
A definition of "marriage" is hidden in her article: ‘Samantha, a cheerful photographer’s assistant from Minnesota, hires Jimmy so she can explore her urge to, as she puts it, “control a man and deny him any happiness.” (It turns out she means handcuffs, not marriage.)’

Control a man, or a woman, and deny him, or her, any happiness. That’s what marriage is all about.

But to many people marriage is like democracy: there’s no viable alternative.
