De Twins

 A mother went into a coma after giving birth to twins

When she woke up after 6 months and 3 days, the doctor told the mother: "While you were in a coma, we had your brother name your children. One is a boy, one is a girl."

The mother, with a disappointed and angry look on her face told the doctor: "Why my brother? That guy is an idiot. So what did he name them?"

The mother, expecting hideous names, prepared herself.

"The girl, was named Denise." The mother thought, "Hey that wasn't so bad. What about my boy?"

The doctor said, "Denephew".
