"Laying Down The Rules" joke

A typical macho man married a typical good-looking lady. After
the wedding, he laid down the following rules:
"I'll be home when I want, if I want and at what time I want...
and I don't expect any hassle from you. I expect a great dinner
to be on the table, unless I tell you otherwise. I'll go hunting,
fishing, boozin', and card-playing when I want with my old
buddies and don't you give me a hard time about it. Those are my
rules. Any comments?"
His new bride said, "No, that's fine with me. Just understand
that there'll be sex here at seven o'clock every night - whether
you're here or not."
