So these 2 nuns are in the school gymnasium cleaing it up to prepare for an upcoming event. It's a very hot summer day and the air conditioning isn't working.

Being so unbearabley hot they decided it would be ok and not a sin to take there clothes off and continue cleaning the gym. So they disrobed, locked the doors and got back to their chore in the nude.

A while later they were startled as someone knocked at the door. They said, "who is it" and the man replied, "blind man." They thought it would be ok to open the door and not to put their clothes back on.

They opened the door and the guy say's "hey, nice T & A, where do you want me to put the venetian blinds."............
