Naming the Twins

A man was taking his wife, who was pregnant with twins, to the hospital when his car went out of control and crashed.

Upon regaining consciousness, he saw his brother, a relentless world-class practical joker, sitting at his bed side.

He asked his brother how his wife was and his brother replied:

- 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 said with trepidation:

- Well what did you name them?

The brother replied:

- I named the little girl Denise.

The husband, relieved, said:

- That's a very pretty name!

What did you come up with for my son?

The brother replied:

- Denephew.
