Book Of The Bible

A boy opens an old family Bible and looks with fascination at the pages as he turns them. Suddenly, something falls out of the Bible. He picks it up and looks at it closely. It’s an old tree leaf that has been pressed in between the pages.
"Mum, look what I found," the shouts boy.
"What is it, dear?" his mother asks.
"I think it's Adam's underpants!"
