Three nuns died and went to Heaven. When they reached Heaven they encountered St. Peter at the Pearly Gates. He informed them that before they could enter Heaven each one had to answer a question. If the answer was correct lights would flash, bells would ring, the Pearly Gates would open and they could enter.
He asked Nun #1, "Who was the first man?" Nun #1 answered, "That's easy - Adam." Lights flashed, bells rang, and the Pearly Gates opened and Nun #1 entered Heaven.
St. Peter asked Nun #2, "Who as the first woman?" Nun #2 answered, "O God, that is an easy one - Eve." Lights flashed, bells rang and the Pearly Gates opened for Nun #2.
St. Peter asked Nun #3, "What was the first thing Eve said to Adam?"
Nun #3 said, "That is a hard one!"
Bells rang, lights flashed, and Nun #3entered Heaven!
