I think he lives in the Alamo, and runs around the Alamo every day wearing different Alamo heads (Alamo heads are giant papier-mache' heads of Davy Crockett, Jim Bowie, Santa Ana, etc.) because he wants people to start calling him "The Phantom of the Alamo." But, to his chagrin, they never will. I don't know why I think this.
