3. Homer is still collecting royalties from The Be Sharps.
How are the Simpsons able to afford a large home, two nice cars, and hundreds of adventures and trips on Homer’s salary? A theory fromRedditpostulates that Homer still receives royalties from The Be Sharps, his Beatles-esque barbershop quartet from the episode “Homer’s Barbershop Quartet.” This theory is supported by the fact that the other members of the band (Barney, Apu, and Principal Skinner) also have unexplained wealth. Barney has a bar tab so high that only NASA can calculate it, Apu drives a nice sports car, and Principal Skinner lives in a nice house in an affluent area.
