Choc, boobs, choc, boobs

A Nun is in the bath when there's a knock on the bathroom door.
"Who is it?" shouted the Nun
"The blind man" came the reply
The Nun tells him to enter, knowing he wouldn't be able to see her in all her glory because he's blind.
He walks in and says "Nice pair of tits, where do you want the blinds?"
