A joke I may have misremembered

A woman gave birth to twins but, due to complications, was unconscious after delivery. Unfortunately, state law required that all newborns be given a name, by a relative on the premises, within 24 hours of birth, or the hospital would provide names for them. Names like "23AFF7." The woman's husband was away on a business trip, so the only relative available was his not-very-bright brother. The woman called her anxious husband when she awoke. "Great news honey! We have a little girl and a little boy!" "Wonderful! What did my brother name the girl?" "Laniece." "That's not too bad. What about the boy?" "Dude."
