Blood Feud is the twenty-second and final episode of Season 2. It was originally broadcast on Fox in August 11, 1991. The episode was written by George Meyer and directed David Silverman. The episode includes the debut of the Olmec head Xtapolapocetl, which would become a common background prop in the Simpson home. It features several reference to the movie, Citizen Kane, and songs such as "Iron Man" by Black Sabbath.
Homer discovers that Bart has a rare blood type that can save Mr. Burns' life, Homer convinces Bart to give blood (in the hopes that Burns will give the Simpsons a cash reward), but when all Mr. Burns gives Bart is a "Thank You" card, Homer writes a nasty letter to his boss...which ends up getting sent to Burns by Bart.
Mr. Burns becomes deathly ill. He is diagnosed with hypohemia, and affliction that leaves a person without enough blood to sustain life. Desperate to save his boss, Smithers issues a plea to the plant's employees for a double-O-negative blood donor. Thinking Burns will reward him richly, Homer volunteers, but he does not have the right blood type. Bart happens to be a match, and Homer has him donate blood to his boss. After the transfusion, Burns is more alive than ever. He even decides to pen his autobiography.
Homer deems Burns' meager thank-you card to be an inadequate response to the gift of life. He immediately writes his millionaire boss a venomous letter, but Marge stops him from mailing it. The next morning, Homer is grateful that Marge's cooler head prevailed and goes to tear up the letter. Unable to the find the hate-filled note, he discovers that Bart has already mailed it. Homer tries unsuccessfully to retrieve the letter, but Burns sees it. Angered, Burns vows to make Homer's life miserable.
First, Mr. Burns signs Homer's pink slip, then he orders Smithers to have Homer beaten to a pulp, but Smithers refuses, explaining that he is unable to harm the man who saved his boss' life. Coming to his senses, Burns realizes the good deed the Simpsons have done, and buys them an extravagant present, a rare Olmec Indian head statue. Bart thinks it is cool, but Homer does not think it is a fitting reward. The family cannot decided on the moral of the story or even if it has one. They do however agree that is has been a memorable few days.
"'Blood Feud" is the twenty-second and final episode of The Simpsonssecond season. It originally aired on the Fox network in the United States on August 11, 1991. In the episode, Mr. Burns falls ill and desperately needs a blood transfusion. Homer discovers Bart has Burns' rare blood type and forces his son to donate some, or he will shoot Bart. However, after receiving the blood, all Burns does is send the family a card. Enraged, Homer writes an insulting reply, but Marge convinces him at the last minute not to send it, although Bart Emails it anyway.
The episode was written by George Meyer and directed by Mark Kirkland. Executive producer Sam Simon and writers Al Jean and Mike Reiss came up with the idea for the episode. A co-worker had recently needed a blood transfusion and the writers thought it would be funny if Mr. Burns had one. Although Meyer was credited with writing the episode, Jean and Reiss re-wrote and polished the script. The episode includes the debut of the Olmec head Xtapolapocetl, which would become a common background prop in the Simpson home.
"Blood Feud" was part of the season two production run, but was completed behind schedule. It was originally broadcast on August 11, 1991 as part of "premiere week", the Fox Network's attempt to expand the normal 30 week prime time season and gain new viewers for the fall. In its original broadcast, the episode finished 24th in ratings for the week with a Nielsen rating of 10.8.
