Blind man
Two nuns are ordered to paint a room in the convent,
with a warning from the Mother Superior not to get even a drop of paint on their habits.
After conferring about this, 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's 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?"
