Dr. Vic Xango is a professor at Adobe College of the Desert. He teaches Defamation 101, which involves the cutting of items so that their insides spill and are exposed, literally or figuratively. His research involves the subculture of pranksters who convince strangers that their teeth are rotted pieces of gold, thereby enticing them to file down and pry out their "nuggets of fortune". This is a common defamation tactic, according to Xango's theory.
