Blood Feud/References

References

• Smithers and Dr. Hibbert discussing about Mr. Burns' health is a reference to Citizen Kane.
• In the Springfield Post Office, a fresco seen above is a parody of The Creation of Adam.
• The head can also be seen in later episodes, in the corner of the Simpsons basement with the rest of the clutter.
• The song that Otto hums while washing his hands is Iron Man by Black Sabbath.
• Homer has mistaken the story Androcles and the Lion and Hercules and the Nemean lion.
• This episode was referenced in the video game The Simpsons: Bart vs. the World in the trivia round. Question: "How did Bart save Mr. Burns' life?" A: He pushed him out of the way of a falling plutonium rod. B: He donated blood to him (correct answer) C: He talked Homer out of murdering him.
• This episode originally aired on the same day Nickelodeon's first three Nicktoons (Doug, Rugrats, and The Ren & Stimpy Show) originally premiered.
• Homer trying to pour liquid into a mailbox only to be stopped by a mail carrier was later reused in The City of New York vs. Homer Simpson, where Homer in that case attempted to urinate in a mailbox only to be stopped by a mail carrier.
• Although it is the second season finale, this episode wasn’t originally meant to be a season finale, as the next episode, Stark Raving Dad was supposed to be instead.

Goofs

• If Smithers' blood type is B-Positive, his kidneys would work on a person with an AB Positive blood type, since they can accept any blood type or another B-Positive person, like Homer. However, a B-Positive person donor is incompatible with a Double O-negative person, meaning that Bart wouldn't be able to use his blood to save Mr. Burns.
• Instead of pretending to be Mr. Burns, why didn’t Homer just tell the man at the post office his real name and that he has to get the letter back he mailed by mistake since his name is on the return address?
• Given its size, how did the Xtapolapocetl enter the Simpsons' residence without any out walls removed?
