A little boy and girl attended the same elementary school and became very good friends. Every day they would sit and eat lunch together.
They discovered that they both brought chicken sandwiches every day. All the way through the 4th and 5th grade, until one day the boy noticed the girl didn't bring a chicken sandwich with her that day.
The boy asked the girl, "Hey, how come you're not eating chicken? Do you not like it anymore?
She said, "I love it, but I have to stop eating it."
"Why?" asked the boy.
She pointed to her lap and said, "Because I'm starting to grow little feathers down there!"
He said, "Let me see."
"Okay," she replied, and she showed him.
He looked and said, "Wow, that's right, you are! You better not eat any more chicken sandwiches."
Then, one day, the boy brought in a peanut butter sandwich and told the girl that he, too, had to quit eating chicken sandwiches. "I'm getting feathers down there too."
She asked if she could see it, so he showed her.
She said, "Oh, MY God, it's too late for you. You've already got the neck and goblets!!!"
