Dib.... is a pimp. Zim is his. Dib owns Zim and always flashes money in Zim's face saying that he owns him and he had bought the alien from the auction. Zim is what Dib calls "his most prized possession." For those who figure out what anime the idea this is from please comment and you shall win a cookie.
