Twins

A man was taking his wife, who was pregnant with twins, to the hospital when his car went out of control and crashed. Regaining consciousness, he saw his brother, a relentless practical joker, sitting at his bed side. He asked his brother how his wife was doing and his brother said, "Don't worry, everybody is fine and you have a son and a daughter. But the hospital was in a real hurry to get the birth certificates filed and since both you and your wife were unconscious, I named them for you." The husband was thinking to himself, "Oh no, what has he done now?" and asked with some trepidation, "Well, bro, what did you name them?" Whereupon, his brother replied, "I named the little girl Denise." The husband, relieved, said, "That's a lovely name! And what did you come up with for my son?" The brother winked and replied, "Denephew."
