Two nuns are ordered to paint a room in the convent, and the last
instruction of the Mother Superior is that they must not get even a drop
of paint on their habits. After conferring about this for a while the
two nuns decide to lock the door of the room, strip off their habits,
and paint naked.

In the middle of the project, there comes a knock at the door.
"Who is it?" calls one of the nuns.
"Blind man," replies a voice from the other side of the door.

The two nuns look at each other and shrug both deciding that no harm can
come from letting a blind man into the room, they open the door.

"Nice boobs," says the man, "where do you want the blinds?"
