Plot

After Homer "wins" a $2000 settlement from the plant due to radiation-induced sterilization, his half-brother Herb sees an opportunity to regain his fortune.

During a routine plant physical, it is discovered that exposure to radiation has sterilized Homer. Mr. Burns pays him off with an elaborate employee appreciation ceremony, and a monetary award. Homer's half-brother Herb Powell, now a hobo, reads about it in the paper, and decide's that Homer's wealth can fund his idea for an invention that would transform baby gibberish into intelligible English.—Tfilm78

Homer "wins" the "First Annual Montgomery Burns Award for Outstanding Achievement in the Field of Excellence", a fictional $2000 prize awarded by Montgomery Burns. The name of the "award" was hastily concocted by Burns on the spot in an attempt to convince Homer to sign a waiver freeing the nuclear plant of all liability for Homer's recently discovered sterility after taking a routine physical exam at work. Joe Frazier is the host of the award ceremony, which features extraordinary extravagance (including a lengthy opening) but only the one $2000 prize is awarded to Homer.

Despite planning on using the money for the Spinemelter 2000 vibrating chair, Homer agrees to loan the money to his bitter half-brother Herb Powell who, ruined by Homer previously, is now a hobo. After hearing a baby cry while in the park, Herb's idea to become rich again is by making a machine to translate a baby's babbling into actual English. He uses Homer's money to develop his invention, which is an instant money-making success. Herb becomes rich once again.

Along with returning the money to Homer, he buys several gifts for the Simpson family, including a new washer-dryer for Marge and the $50 he got from selling them (the old, broken washer and dryer are sold to Moe's Tavern where they are subsequently engaged in racing), an honorary membership to the NRA for Bart (since he is too young to own a gun just yet), and a subscription to the Greater Books of the Western Civilization for Lisa. He promises to give Magggie something nice for her. Herb then tells Homer that his gift to him is forgiveness for ruining him in the first place, and he and Homer re-establish a brotherly relationship. Finally, Homer is rewarded for his generosity and faith when Herb has a truck pull in with the Spinemelter, which Homer enjoys. The Spinemelter also rejuvenates his once lethargic sperm as shown in the last shot of the episode.
