Looking to boost sales, Costington's Department Store invents a new holiday, Love Day, which prompts Springfield residents to buy one another gifts such as "Sir Loves-A-Lot, the bear who loves to love." However, all those boxes and wrapping paper mean plenty of trash, and Homer Simpson (voice of Dan Castellaneta), typically late in taking the trash out to the curb, curses the sanitation workers when they don't pick up his rubbish. The angry garbage men refuse to pick up the Simpsons' trash until Homer apologizes, which he's highly reluctant to do. Eventually, Marge (voice of Julie Kavner) apologizes on her husband's behalf, which leads to an angry confrontation between Homer and Ray Patterson (voice of Steve Martin), Springfield's sanitation commissioner. Homer decides to put Patterson out of business by running for sanitation commissioner himself, and after making a number of ridiculous promises and slandering his opponent, Homer wins the office. However, Homer's ambitious plans cause him to blow through his annual sanitation budget in less than a month, and to cover up his mistakes, he starts accepting dangerous waste from other cities until Springfield's landfills are overflowing. First aired on April 26, 1998, "Trash of the Titans" also features a guest appearance from Bono, The Edge, Adam Clayton and Larry Mullen of the rock group U2 as themselves.
