Am I a genuine polar bear?

A young polar bear goes up to his mum and asks (stuttering)

'Mum, a.a..am I a gen..gen...genuine p..polar bear?'

The mum replies
'Of course you are son. You have polar bear claws, polar bear nose, polar bear fur. Of course you are a genuine polar bear.'

'T.t..thanks mum'

The young polar bear then goes up to his dad.

'Dad, a.a..am I a gen..gen...genuine p..polar bear?'

The dad replies
'Of course you are son. You have polar bear claws, polar bear nose, polar bear fur. Of course you are a genuine polar bear. Why would you even ask?'

The young polar bear replies
'We..well d..d..dad, be..be..because I'm f..f...fucking freezing!'
