Paddy'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 fine now, but they were doing poorly at birth and had to be christened immediately... Your brother came in and named them.'

The woman thinks to herself, 'Oh no, not mi' brother! He's a bloody clueless ignoramus!'  

Expecting the worst, she asks the doctor, ‘well, what's my daughter's name?'

 'Denise,' says the doctor. 

The new mother is totally relieved.   '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'

Methinks: The brother is still a genius in some quarters...some people I know can't even figure out the joke...Lol!
