A Big Piece of Garbage

Tonight is the annual inventors symposium, and the Professor is hoping that his invention is good enough to win the prize and beat Dr. Wernstrom. He presents the Smelloscope, a device that allows one to smell distant objects. Though he is laughed off the stage by his peers, the crew tests it out back at the Planet Express. Fry discovers what is believed to be the smelliest object in the universe. They learn that the object is a giant ball of garbage that was rocketed into outer space fifty years ago. Now, it's up to the Planet Express crew to figure out how to stop the garbage ball before it crashes to the earth and destroys New New York.
