Paddy has broken his leg and his buddy Mick comes over to see him.

Mick says, "How you doin?"

"Paddy says, "Okay, but do me a favour mate, run upstairs and get me slippers, me feet are freezing."

Mick goes upstairs and sees Paddy's gorgeous 19-year-old twin daughters lying on the bed.

He says, "Your dad's sent me up here to have sex with 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 fu*kin one?"
