Charlie (Originally Crazy Horse)

Real Name: Aaron Feather
Story: He was in my history class, and the class was playing a review game at the chalkboard, where one person from each team would go to the board, the teacher would ask a question, and whoever wrote the correct name down the quickest got a point.
It was my turn, the teacher asked the question, and I had no idea what the answer was.
Charlie gave me the answer, by whinneying like a horse.
After telling my friends the story, Amber once accidentally called him Charlie horse, so we all started calling him Charlie.
