Mr. Burns is gravely ill and needs a blood transfusion, and Bart is the only compatible donor. Homer encourages Bart to donate, anticipating getting a big reward from Burns in exchange for saving his life. When Bart gives his blood and no reward comes (only a thank-you card), Homer gets angry and writes a nasty letter to Burns. Marge intervenes and talks Homer out of mailing the letter.
