Leaves
Adam and Eve believed they were part of a canvas. Their lives in the garden were being painted.
Of course, they had to make sure it was a politically correct painting, so rather than just walk around naked like normal people, Adam and Eve carried leaves to hide their... delicate extremities.
"You know," Adam said one day. "I think I've been holding this leaf in front of my dick for too long."
"How do think I feel?" Eve snapped. "I have no free hands! I have to cover my chest and my glory hole. I can't even itch my nose!"
"Yikes," said Adam. "Want me to do that for you?"
"Yes! Please! You have no idea how horrible it's been!"
And so Adam came over to Eve and itched her nose. And then backed up very quickly, eager for the conversation to be over.
"Ack! It's already itching again!"
