The episode kicks off with a segment set in ancient Mayan times, parodying the film Apocalypto . It plays on the then-current "2012 end of the world" craze, depicting a failed blood sacrifice that leads to giant Mayan stone gods awakening in the present day to destroy Springfield.
Despite Lisa’s warnings, the family begins using the black hole as a convenient trash disposal for everything from grease to Edna Krabappel.
