"Golden Boy" is the final episode of the series All Grown Up!. It is the 10th episode of Season 5 and the 55th episode overall. It was the final Rugrats production to date, until the Rugrats (2021 series), and is the final installment of the original 1991 continuity of the franchise.
The episode begins with Lou holding a garage sale outside the Pickles house; he gives an old car to Drew and Stu, whereas Didi gets a shredder and starts to go crazy with it. After Lou tells Tommy about a baseball game, Tommy says he has a date with Rachel; so Lou takes Dil instead. Tommy starts to get jealous of Dil. When Lou takes the boys hiking, they start fighting to see who is the best grandson. After Lou fakes to be knocked out, the boys take him back home, feeling sorry for fighting. Later, Stu and Drew destroy the old car and Lou gets mad because it belonged to Elvis Presley. Lou writes the boys a note at the hospital and gives it to them, but Didi shreds it. Later that evening, Tommy pieces the shredded note back together and he and Dil soon discover that Lou's fainting was a prank - the note said "Gotcha".
