Malcolm X High
In Malcolm X High, it shows that the name "Buckethead" was given to this weirdo because he always wore a bucket for a hat. He came from a poor family, so they couldn't afford to get a hat for him. So during the winter, he'd wear something on his head called a bucket. And that's how "Buckethead" came into existance.
