Billy Bob's pregnant sister...

was in a terrible car accident and went into a deep coma. After being in the coma for nearly six months, she wakes up and sees that she is no longer pregnant. Frantically, she asks the doctor about her baby.

The doctor replies, "Ma'am, you had twins! A boy and a girl. The babies are just fine."

"After all this time," she says, "do they have names?"

"Yes ma'am," the doctor says. "Your brother came in and named them."

The woman thinks to herself, "Oh no, not my brother... he's ...Well, not the brightest bulb in the family pack."

Expecting the worst, she asks the doctor, "Well, what did he name them?"

"The girl is Denise," says the doctor.

The new mother says, "Wow, that's a beautiful name! I guess I was wrong about my brother. I like Denise." Then she asks, "What's the boy's name?"

"Denephew"
