A few one-liners I particularly liked about the difference between the sexes :
a successful man is one who earns more than his wife can spend. A successful woman is one who can find such a man.
A woman marries a man expecting that he will change, and he doesn't. A man marries a woman expecting that she won't change, and she does.
A woman has the last word in any argument. Anything a man says after that is the start of a new argument.
