Adam's Underwear

A little boy opened the big family Bible. He was fascinated as he fingered through the old pages. Suddenly something fell out of the Bible. He picked up the object and looked at it closely. What he saw was an old leaf that had been pressed in between the pages.
"Momma, look what I found," the boy called out.
"What have you got there, dear?" his mother asked.
With astonishment in the young boy's voice, he answered: "I think it's Adam's underwear!"
