Bubba was extremely proud that he was going to be an uncle for the first time and even better his sister was giving birth to twins.
The only bad news in the whole situation was that his Brother-in-Law was out of town when unexpectedly his sister went into labor.
Being the man that he is Bubba volunteered to help his sister in her hour of need.
After a long and ardous 20 hour labor she gave birth to a beautiful set of twins one boy and one girl.
While she was recovering after the birth she told the nurse that if she had any questions she should ask Bubba and let her rest.
While the hospital staff was getting all their paperwork filled in they noticed that the form for the birth certificates was incomplete they children had no names.
When they asked Bubba about it he replied "Oh I know that to call them."

We'll name the girl Denise and the boy Denephew.
