Three nuns die and go to heaven where they are met by St Peter at the pearly gates. St Pete says "Ladies, you all led such wonderful lives, that I'm granting you six months to go back to Earth and be anyone you want".
The first nun says "I want to be Bo Derek," and POOF she's gone.
The second says "I want to be Madonna," and POOF she's gone.
The third says "I want to be Virginia Pepalini.".
St Peter looks perplexed. "Who?" he says.
"Virginia Pepalini" replies the nun.
St Peter shakes his head and says "I'm sorry, that name just doesn't ring a bell.
The nun then takes a newspaper out of her habit and hands it to St Peter. He reads the paper and starts laughing.
He hands it back to her and says "No Sister, this says the Virginia Pipeline was laid by 500 men in 7 days!".
