Paddy has broken his leg and his mate Mick goes round to see him.

Mick says, ‘how you doin?’

Paddy says, ‘do me a favour if ya might.  Nip upstairs and get me slippers, me feet are freezing.’

Mick goes upstairs and sees Paddy’s gorgeous 19 year old twin daughters sitting on the bed.

He says, ‘your dad’s sent me up here to shag the both of you’

They say ‘get away with ya… prove it.’

Mick shouts downstairs, ‘Paddy, both of em?”

Paddy shouts back, ‘of course both of em.  What’s the point of f*****n one?’
