Three nuns die and end up at the gates of Heaven. St Peter says that before they can enter, they must first each answer a question. To the first he asks ""who were the first humans?"" She says ""Adam and Eve"" and he lets her in. To the second he asks ""where did they live?"" She says ""In the garden of Eden"" and she too is admitted. Then he asks the third, ""what was the first thing Eve said to Adam?"" She replies ""My goodness that's a hard one"" - and he opens the gate and lets her in.
