Mike and Gloria are having a discussion over who will take care of Joey, just in case there comes a time when both of them are unable to care for the little tyke before his 18th birthday. Mike has serious reservations over allowing in-laws Archie and Edith to get custody of Joey, particularly due to what he perceives as Archie's bad influences. Gloria is having a hard time convincing Mike otherwise and gives in to Mike's rhetoric. Mike's suspicions are confirmed when Archie and Edith return with Joey after a day of playing in the park. What's that Joey's got in his hands? Why, a toy machine gun that Grandpa had bought him. Of course, Mike (being dead set against gun violence) immediately is very angry and tells Archie that toy guns could influence children's behavior later on. Tempers really escalate when Mike grabs the plastic gun from Archie and breaks it over his knee. After the two continue to argue, Mike lets slip that he is considering including a clause in the Stivics' will that will grant custody of Joey to friends, if something should happen to both Mike and Gloria. Now Archie becomes really, really, really, really angry at his son-in-law, but unexpectedly (but understandibly so), so does Edith. After Archie storms out to allow relieve his very high blood pressure, a calmed-down Mike tries to reason with Edith, saying that he has no problems with her, the problem is Archie. But Edith shoots back, reminding Mike that, although Archie is far from perfect, he is a good man and loves Joey, and that he would always do what was right for his grandson and never do anything that was morally objectionable. After Mike and Gloria talk it over some more, and Gloria also comes to her father's defense, they decide ... not to make a decision right now. The decision seems to sooth Edith and satisfy Archie. But Archie still has one matter to clear up that toy gun; he wants Joey to have a toy machine gun and, in the coda, tries to get the money to pay for a new one out of Edith's purse!
