3 nuns are in a bus in Colombia, which due to budget cuts breaks it's axle, rolls over, and kills them all. When they come to, they realize that the three of them are in a cloud-filled place standing in front of an elderly man at a dais, behind whom are enormous, gold-plated gates, which at the moment are closed.
The man says to them "Welcome, my friends, to the Pearly Gates. My names is Peter, and I am the gatekeeper".
The nuns, thinking that they have devoted their lives to the service of God, are relieved to find out that this is where they are. As they step forward, Peter says "you three have been such devoted servants of the lord that we will all rejoice to have you in heaven... given that you can answer one question each."
The nuns are, understandably, taken aback. Peter asks, "So, who would like to go first?"
Two of the nuns step back, leaving the third standing in front.
Peter asks "So, my friend, what is the name of the first man?"
The nun doesn't even have to think... "That's an easy one - Adam". The bells ring, the angels sing, and the first of the three is welcomed to heaven.
At this, the 2nd nun steps forward, having a bit more confidence. Peter asks... "What is the name of the first woman?" The nun answers, without hesitation "That's an easy one - Eve". The bells ring, the angels sing, and she too is admitted to eternal glory.
Finally, the last nun is at this point relieved that the questions seem to be such trivial pieces of knowledge to those so pious as them, so she steps forward. Peter asks... "What was the first thing that Eve said to Adam".
The last nun then quakes a bit as she realizes that this question, unlike the others, isn't quite as trivial. She bites on her lip as she says "Oooh... that's a hard one..."
The bells ring, the angels sing, and the last nun enters the realm of eternal glory as well.
