It was a hot summer day and two nuns were painting a room in the convent.

As there was no air conditioning the heat soon became unbearable. The first nun said that they should remove their clothes so that they would be cooler.

The second said what if someone should come?

The first said well lock the door and then we will be safe. So they lock the door and continue painting when there is a knock on the door.

The first nun asks who it is and the reply comes back It is the blind man.

The two nuns confer and decide that the blind man cant see anything and let him in, at which time the man says Nice tits sisters, where do you want these blinds?
