Naughty Joke...and Very British

This joke is labeled "controversial" in deference to any Christians who may read it and be offended at the thought not only that Adam and Eve were sexual beings, but that Eve enjoyed and (God forbid!) may even have been turned on by the sight of an erect penis on her man!  Please enjoy responsibly!   

I was just watching "The Vicar of Dibley". At the end of the show, Geraldine, the vicar (Dawn French), tells a joke which Alice, her assistant, never gets. Here was tonight's joke.
Three nuns die and go to heaven. At the gate, St. Peter meets them and informs them that they have to answer some questions correctly in order to be allowed to enter. He asks the first nun what was the name of the first woman, and she says, "Eve", and he lets her in. The second one he asks where Eve lived and she said "The Garden of Eden", and he lets HER in. The third one was the Mother Superior, and he told her that her question would have to be more challenging than the other two. He asks her what Eve said when she first saw Adam, and she said, "Oh, that's a hard one!" To which St. Peter replied, "That's right! Well done!" and let her in.
