strip off their habits, and paint in the nude.
In the middle of the project, there comes a knock at the door.

"Blind man," replies a voice from the other side of the door.
The two Nuns look at each other and shrug, and, deciding that no harm
can come from letting a blind man into the room, they open the door.
"Nice tits," says the man, "where do you want these blinds?"
