I forget who it was who told me about the three nuns trying to get into heaven. 

St Peter met them at the Pearly Gates and said, "You'll each have to pass a little test before I can let you in." Turning to Nun Number One, "Who was the first man?" She said, "Oh my, that's an easy one. It was Adam." St Peter said,"OK, go on in," and she walked through the Pearly Gates.

Then turning to Nun Number Two, "Who was the first woman?" She replied, "Oh my, that's an easy one. It was Eve." "OK, go on in."

Turning to Nun Number Three, "What were Eve's first words when she saw Adam?" She looked puzled, "Oh my, that's a hard one..." "OK," says St Peter, "Go on in."

Oh crap. And I thought I was being so original!
Ha!
So much for having a "senior moment" while telling jokes.
