The Simpsons take advantage of one-time-only free classes at the YMCA. While Marge learns self-defense, Homer plays in the "Over 35 Basketball League" and promptly blows out his knee. During surgery, Homer falls off the gurney and injures his back, leaving him unable to work. Bored and lonely, Homer opens a home daycare center to keep himself occupied. To everyone's surprise, "Uncle Homer's Daycare" is a huge success and earns him a nomination at the "Good Guy Awards". Meanwhile, Bart and Lisa become jealous of Homer's attention towards other kids. They decide to edit the award show with some of their home videos. When Homer is presented with his trophy, the sabotaged footage is revealed and exposes him as a "beer-drinking meanie".
