Synopsis
Fearing death, Grandpa Simpson tells Homer that he has a half-brother. This half-brother, Herbert Powell, is a carmaker in Detroit, and wants Homer to design a car for the average man to save his car company. The Herb-and-Homer storyline is continued in the episode's sequel, "Brother, Can You Spare Two Dimes?".

Full Story
After watching the latest McBain movie, Grampa Simpson suffers a case of a mild myocardial infarction while complaining to the theatre's manager. This prompts him to confess a long-hidden secret; Homer has a half-brother.

As Grampa explains, he had met a carnival floozy and prostitute before marrying Homer's mother. They had a son, and left him at the Shelbyville Orphanage. Determined to find his brother, Homer and his family go to the orphanage and find out that Abe's son was adopted by a Mr. and Mrs. Powell and named Herbert.

Herb Powell (who looks just like Homer, except with more hair and a little less gut) is the head of Powell Motors car company (in danger of being taken over by the Japanese because of otherwise poor management). He is very rich, but is quite unhappy not knowing who he is and where he comes from. He is overjoyed upon hearing of his half-brother and invites the entire Simpson family to stay at his mansion in Detroit.

Bart, Lisa, and Maggie are enthralled by Herb's wealthy lifestyle (though Marge constantly worries about spoiling her kids), and Herb decides that Homer, being an "average" American, is the perfect person to design a new car for his company, which has been losing business due to foreign car manufacturers. Herb introduces Homer to his company's design team, who soon use his lack of vehicle knowledge to try and design 'their' perfect vehicle. Back in the hospital, Abe is informed by Homer about Herb's wealth and business. Before he leaves, Abe warns his son to behave himself and not do anything dumb to ruin Herb.

When Herb asks Homer how the car design is coming along Homer can't give him a straight answer. Herb feels that Homer is not being forceful enough with his ideas, and gives Homer a pep talk. Pretty soon, Herb has invigorated Homer, who returns to the designers and begins demanding weird items like bubble domes, fins and several horns that play "La Cucaracha". While Homer becomes more a businessman, Herb spends time with Marge and the kids, becoming more of a family man like Homer. Herb's money and prestige enables the kids to enjoy life in style, but Marge is worried they may becoming spoiled. Herb reassures her they'll be fine and wonders how Homer is holding up.

At the unveiling of "The Homer", Herb is horrified to discover that the car is a "monstrosity" that costs $82,000 (which is more than he has). Herb's company folds, his mansion is sold off and he leaves regretting that he ever met his brother. As he departs on the bus to Detroit, he angrily remarks to Homer that he "has no brother". Lisa laments on Herb's life in how he was a successful businessman with a wealthy life until he discovers he is a Simpson. When a healthy Abe came over from Springfield to meet with Herb, he discovers to his detest that Homer ruined his brother's life by bankrupting him in creating a car that is a disaster. Abe decries Homer for screwing up everything and declares he has no son after this. In the end of this episode, while Homer drives the family home, Bart tells him that the car he built was great. He became relieved that at least one person he cares about seems to like it.
