Xmas Story

] Frank Welker voices Fry's parrot and created the annoying squawk used. The initial squawk he made was considered to be annoying but according to Cohen they had him continue to make the squawk more annoying until he had done nearly a hundred different parrot squawks.

In this episode Bender receives a card from the machine that built him, referring to him as "Son #1729", a reference to the Hardy-Ramanujan number. According to Ken Keeler, co-executive producer of the series, they could have chosen any number but chose to include an interesting one instead. Many of the math and science jokes in the series found their way into "Futurama" in this way.]

Continuity

* Bender recalls giving blood, but cannot remember whose blood it was. In the episode "Godfellas", it is revealed to be Fry's blood.
* The other "Futurama" Christmas episode, also dealing with Robot Santa, is "A Tale of Two Santas" (though the Robot Santa is not voiced by John Goodman in "A Tale of Two Santas").
* Robot Santa also appears in "Bender's Big Score".
* In this episode it is stated that global warming occurred but was cancelled out by nuclear winter. In "Crimes of the Hot", it's revealed that global warming is still around (and quelled by putting a large ice cube in the ocean), while in "Less Than Hero" the mayor calls global warming a hoax (just like secondhand smoke).
* Zoidberg claims to be cold-blooded, this fact caused the heat seeking missile to not attack the Decapodian oppression palace in the season four episode "A Taste of Freedom".
* Although it is stated in by Professor Farnsworth that French is a dead language, a sign on a store reads "joyeux noex," in Alienese, keeping with the theme of referring to Christmas as Xmas and also in "Teenage Mutant Leela's Hurdles", Pazuzu, The Professor's Gargoyle, speaks French.
* When the characters go to cut down Xmas trees, they only find palm trees. Fry asks why, and Professor responds by telling him that pine trees have been extinct, yet in the scene before, there were forests of pine trees (most likely artificial).
* Fry receives Xmas cards although his only family is the professor, and he has no friends except for Leela, Bender, Hermes, Amy, the professor, and sometimes Zoidberg. The cards couldn't have come from his co-workers as Leela would have got some.
*When Bender opens up his Xmas card, we see a picture of a machine, which Bender states is his mother, although, in previous and future episodes, Bender's mother happens to be Mom, creator of all robots. Although in another episode he has a flashback of his mom (an assembly line machine) building him. Most likely he considers both to be his mom.

Bongo's Appearance

Bongo, from Matt Groening's "Life in Hell", is one of the animals being sold at the pet shop that Fry goes to.
