Husband comes home late at night and quietly opens the door to his Bedroom. From under the blanket he sees four legs instead of two. He reaches for a Baseball Bat and starts hitting the blanket as hard as he can. Once he's done, he goes to the kitchen to have a drink. As he enters, he sees his wife there, reading a magazine.
"Hi Darling", she says, "Your parents have come to visit us, so l let them stay in our bedroom. Hope you have said Hello ?
