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,
she goes to the kitchen to have a drink.

As she enters,
she sees her husband there, reading a magazine. :s

"hi darling", he says,
"your parents have come to visit us,
so I let them stay in our bedroom.
Hope you have said hello to them.
