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, 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"?
