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. "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."

funny!
