One day a group of friends were walking in the park and an annoying kid came and asked to be in their group. So the other kids talked it out and said yes. They walked and walked, suddenly the annoying boy asked what they got on their report card. Everyone said A's and B's, the little boy said
"A's....B's....C's....... Z's....." and he laughed in a monkey sounding noise then a boy out of the group said " man on your report card, you got ADHD"
