Given the scatological theme of this thread, I am reminded of a joke. A father is sitting alone in his easy chair in the living room one evening after dinner, and silently breaks wind. Soon thereafter his little daughter enters the room and stops dead, cautiously sniffing the air. "Daddy," she said, "I know where that odor comes from." Amused, the father decided to play along, and so replied, "Where, Honey?" "From another planet," she replied with grave sincerity. Not being the answer which he was expecting, he looked at her with a puzzled expression and asked, "Which one?" The little girl, beaming as though she had just won the Nobel Prize, said, "All the way from Uranus!"
