Nuns Painting a Church

There were 3 nuns about to paint a church. but right before they started one of the nuns realized that if they got paint on there habits, they couldn't be nuns anymore, so they started to paint naked when suddenly the door rang.
One nun yelled, “who is it?”
The person at the door yelled back, “Its the blind man!”
So they thought that if they opened the door the man wouldn't see them naked because he’s blind.
So they open and the door and the man said, “Hey nice jugs, where do you want your blinds?
