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 and cool down.. As she enters, she sees her husband there, reading a magazine.
“Hi, sweetheart,” he says. “Your parents have come to visit us,so I let them stay in our bedroom. Did you say hello?”
