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.
Once she’s done, she goes to the kitchen to have a drink.
She enters the living room, sees her husband there, reading a magazine.
“Hi Darling” he says. “Your parents have come to visit us, so l let them stay in our bedroom. Did you say hello?”
