The wife fainted [joke]

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. :she said
 "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?
