three nuns die and go to heaven where they are met by st.peter at the pearly gates.
st peter says to the first nun "what was the name of the first man?"
1st nun: "that's easy, the answer is adam."
st peter replies: "ok, you're in"
the first nun goes through the pearly gates.
st peter turns to the second nun and asks: "what was the name of the first woman?"
2nd nun: "this is easy as well- it was eve."
st peter: that's the correct answer, you may also enter heaven." so she joins her sister on the other side of the gates.
st peter then turns to the third nun and says:
"now, as you're mother superior, your question will naturally be more difficult."
the nun replies:"ok, shouldn't be problem"
st peter thinks for a moment and says:"what was the first thing eve said to adam?"
the mother superior thought for a long, long time and eventually replied:" ooh, that's a hard one"
