The chapters are all just two or three pages, each presenting some double standard with a catchy name, describing the problem and suggesting a remedy. Some examples (in addition to the title one):
He's a man, she's a mom.
He's chill, she's on the pill.
He's tough, she's a tomboy.
He's gay, she's a fantasy.
He's the boss, she's a bitch.
He's manly, she's Sasquatch [regarding hair removal].
He's lucky, she's Lolita.
He's distinguished, she's driving Miss Daisy.
He can be a beast, she must be a beauty.
And so on. I don't think I agree that all of them predominate all the time, but they are thought-provoking. (If any need further explanation, let me know). At Amazon, as you can see, you can look inside the book. I saw it in a bookstore and could not resist.
