There comes a time when a woman just has to trust her husband...

For example...

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.

She reaches for a baseball bat and starts hitting the blanket as hard as she can.

Leaving the covered bodies groaning, she goes to the kitchen to have a drink.

As she enters the other bedroom, she sees her husband there, reading a magazine.

"Hi Darling", he says, "Your parents have come to visit us, so I let them stay in our bedroom. Did you say "hello"?
