Chicken Skin
When I was a teen I had this friend who was a selfish jerk. One night at supper time he screamed and yelled at his parents that he wanted Kentucky Fried Chicken and he did so till his dad went to get some.
When his father came back he sat at the table and grabbed each piece of chicken and ripped off the skins and walked away with them. That is all he wanted to eat. I was mortified and stunned.
His parents took it as another day. Oh and he also destroyed his stereo because he wanted a new one and he knew his parents would buy it for him. Story credit: Reddit / Gunboat_Willie
