Chicken sandwich

Everyday this boy and girl came to school and brought a chicken sandwich for lunch. One day the girl didn't bring a chicken sandwich to school so the boy asked her why she didn't bring a chicken sandwich.

The girl said I can't eat chicken anymore because I'm sprouting feather. The boy said let me see. So the girl pulled her pants down and showed him, he said oh I see.

The next day the boy didn't bring a chicken sandwich and the girl asked him,"Why didn't you bring a chicken sandwich?"

The boy said,"I'm sprouting feather also." The girl said let me see. So the boy pulled his pants down and showed her and she said,"Wow you are sprouting feathers, you also sprouted a neck and two gizzards.
