A woman gave birth to twins, a boy and a girl, in the hospital. Only her brother was present with her. After the delivery, the nurse entered the room and said, "Your brother has taken the liberty to name the children."
The new mother sighed, "Oh no. He probably gave them stupid names."
"The girl's name is Denise," the nurse replied.
"That's not bad, I like it," the mother said. "And the boy's?"
The nurse answered, "The boy's name is De-nephew."
