Unexpected

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.  Once she's done, .. with a sense of pride and satisfaction 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.
