The prayer room in the seminary was to be painted. Two of the nuns were ready to do. Since they did not want their robes to be messed up by paint, they decided to take of their robes off and paint the walls naked. They closed the prayer room door and start painting. After some time they hear a knock. Puzzled they asked
“Who is there?”
“The blind man” was the answer.
The nuns thought that since it was the blind man, he can’t see that they are naked. So they opened the door, the man asks “I got the blinds for the window. Where do I keep them”?
