Three nuns die and are at the gates of heaven and St. Peter pops up and says "Before you enter heaven you must each answer one question correctly".

The first Nun was asked "Who was the first man on earth?" to which she replied "Adam" and was allowed into heaven.

The second Nun was asked "Who was the first woman on earth?" to which she replied "Eve" and was allowed into heaven.

The third Nun was asked "What was the first thing Eve said to Adam?" to which she replied "Ohh! That's a hard one"
