Garfield tries not to buy any more useless things following a threat from Jon.
Jon is returning home from work when someone exits the Arbuckle house with enough money to take a vacation. Jon is convinced that Garfield is buying stuff without his permission and he enters the house in a rage, slamming the door in the process, which Garfield points out as Jon scolds him for wasting his money on overpriced useless pieces of junk. He goes back out, threatening Garfield with no lasagna for the rest of his life if he buys one more thing.
Garfield finds the thought of a lifetime lasagna ban unbearable and goes to watch television. He eventually finds a shopping channel, where a salesman, Herbert Finagle, offers viewers a Laser-Powered Elephant Repeller. Garfield who does not yet have such a product, runs over to the telephone, only to remember Jon's threat from earlier ("no lasagna for the rest of your life") and tries to resist. The devious salesman then announces that the first 20 callers will get their repeller free. Garfield is then fully convinced to buy the product.
Finagle arrives in his fancy convertible and is about to give Garfield his free Elephant Repeller, when he realizes that Garfield owes him $28 in charges. Now realizing he has been tricked, Garfield slams the door in his face, refusing to pay such a hefty price, and goes back to watching the TV. However, Finagle climbs through the window, and Garfield throws him out the door. Garfield's efforts to keep Finagle away prove fruitless, as he shows up everywhere Garfield goes.
Garfield barricades the door and decides to hide under the bed, only to realize that Finagle is hiding under there too. He hides in the basement, where Finagle is hiding as well. Upon hearing about a guarantee, Garfield gives up and buys the product. Jon comes back home as Finagle tells him that he will offer them a thousand dollar money-back guarantee if the repeller doesn't keep elephants away. Jon then yells at Garfield.
Finagle is about to leave when he hears an elephant's trumpet. He realizes to his horror that three elephants have appeared outside the Arbuckle house, and he falls to the floor sobbing as now, true to his word, he owes Jon, Garfield and Odie a thousand dollars, which Garfield suggests he can now spend on a Microwave Cheese Straightener.
