Puberty Joke

A little boy and a little girl attended the same school and became friends. Every day they would sit together to eat their lunch. They discovered that they both brought turkey sandwiches every day! This went on all through the fourth and fifth grades until one day he noticed that her sandwich wasn't a turkey sandwich.
He said, "Hey, how come you're not eating turkey, don't you like it anymore?" She said, "I love it, but I have to stop eating it."  "Why" he asked? She pointed to her lap and said, "Cause I'm starting to grow little feathers down there!"  "Let me see" he said.  "Okay." and she pulled up her skirt. He looked and said, "That's right you are. Better not eat any more turkey."
He kept eating his turkey sandwiches until one day he brought peanut butter. He said to the little girl, "I had to stop eating turkey. I'm starting to get feathers down there too." She asked if she could look so he pulled down his pants for her. She said "Oh, my God, it's too late for you, you've already got the neck and gizzards!!!"
