Watch a lot of episodes of Hey Arnold. Watch the girl named Nadine. She is the one with all the braids. Her hair is either yellow or brown. In my opinion, this is big because even though her hair is supposed to be yellow, somepne kept screwing up and making it brown. I wonder why they didn't catch it? It isn't like it's two different people, either. Her hair will be yellow in one shot and brown in the next. Weird, no?
