There comes a time when a woman just has to trust her husband...
A wife comes home late at night and quietly opens the door to her bedroom. From under the blanket she sees four legs instead of two. A man and a woman. She reaches for a baseball bat and starts hitting the blanket as hard as she can. Once she's done, she goes to the kitchen to have a drink.
As she enters, she sees her husband there, reading a magazine.
"Hi, Darling", he says, "Your parents have come to visit us, so l let them stay
in our bedroom. Did you say ‘hello’?”
