Three Italian nuns die and go to heaven where they are met by St. Peter at the pearly gates.
St. Peter 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 Sophia Loren" 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 Sara Pipalini".
St. Peter looks perplexed. "Who?" he says.
"Sara Pipalini" 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. "No Sister, he laughs, this says 'Sahara Pipeline, laid by 500 men in 7 days'!"
