When Moe is heckled for not having any real friends, his best friend (his bar rag that he likes so much) narrates the story of how he got to Springfield, from The Middle Ages to where he is today. Meanwhile, Bart and Milhouse have a fallout at Moe's Tavern after Bart takes something too far, so he sets out to whatever he can to get Milhouse's forgiveness. Then, Moe realizes he doesn't need to have just a bar rag as a friend.
