A nun's joke

Three Italian nuns die and go to heaven, where they are met at the Pearly Gates by St. Peter. He 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-a to be Sophia Loren" and poof! she's gone.

The second says, "I want-a to be Madonna" and poof! she's gone.

The third says, "I want-a 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 but 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 'Sahara Pipeline laid by 500 men in 7 days'!"
