One day a lady arrives home late at night and silently enters her bedroom.
She finds four legs on bed inside blanket, two male and two female!
She takes a rod in her hands and starts hitting and shouting crazily.
“What happens, why are u shouting” her husband ran into the room.
“Oh you are here! then who are on the bed?” wife asks.
“Your parents came, i let them sleep in our bedroom” replies husband.
