Trivia: At around 5 mins 11 seconds into the episode, Vincent Nigel-Murrey and Dr. Saroyan are discussing the bones on the forensic platform. In the background of a shot of Vincent, the x-ray on the screen is of Homer Simpson's head in the middle of the screen, instead of a real human skull.
Trivia: When Max and Temperence go out to lunch with Temperence's cousin Margaret, Max comments that the pair are "practically sisters," and later when Margaret meets Booth, Booth asks if she is Bones' sister. The actress playing Margaret is actually Emily Deschanel's sister, Zooey.
Trivia: Kathy Reichs, whose novels and experiences the series is based on, appears as one of the professors questioning Zack about his dissertation. (00:00:50)
Trivia: The plotline of this episode is based on copycat murders drawn from Bones' books. The fictitious heroine in the book is named Kathy Reichs: Reichs is the forensic anthropologist upon whose life the character Temperance "Bones" Brennan (the character in her books and this series) is based.
Trivia: At the diner in Roswell, Booth sees a picture of Dave Roberts, the host of the children's morning radio show "Rocketship 7", and mentions the show by name. Roberts is actually David Boreanaz's father.
The Girl with the Curl - S2-E7
Trivia: The pageant where the girl was kidnapped from was taking place at the Hyperion Hotel. That was the same name of the hotel in the show Angel, David Boreanaz's previous show.
Trivia: The position of the bodies and in particular the arms of the two dead, corrupt FBI agents bear a remarkable resemblance to a full size painting that appears in Angela's throughout the first season and most of the second season of Bones - body upright, upper arms outstretched and forearms pointing down at a right angles.
Trivia: This episode pays homage to The X Files, even using the X Files theme tune for a ring tone. It also features Dean Haglund, playing Blaine Miller who owns the alien themed cafe. Haglund also played Langley, one of the lone gunmen from The X Files.
The End in the Beginning - S4-E26
Trivia: When Booth starts seeing Stewie Griffin (from Family Guy) because of his brain tumor, all of Stewie's dialogue was written by Seth MacFarlane.
Player Under Pressure - S3-E11
Trivia: This episode's airing was postponed for almost a year following the Virginia Tech massacre. Coincidentally, a similar event happened to David Boreanaz almost exactly eight years earlier when the "Buffy the Vampire Slayer" episode "Earshot" was postponed following the Columbine school massacre.
Trivia: Throughout the show, almost all documents, including things that most people would just write on a Post-It note, are on the Jeffersonian Medico-Legal lab letterhead. That is very unusual behaviour for documents that are not official, legally-required. Day-to-day paperwork would be on regular, standard white blank pages. The cost of their fancy, logo letterhead being used all the time would be prohibitive in any other workplace.
Trivia: Dean Haglund, who plays the restaurant owner in this episode, was one of the Lone Gunmen, Richard Langley, in the X-Files series itself.
Trivia: The number 447 frequently appears in the show. An example of the number appearing is in season 9 episode, The Secrets in the Proposal - At the very end of the episode, after Brennan and Booth reconcile, the clock in their kitchen reads 4:47, but then switches to 7:35. Booth's alarm clock shows that time in The End in the Beginning, and it appears as a room number and in a newspaper headline in The Crack in the Code. It is also the time (4:47) that the bombs go off in the final episode.
Trivia: Aside from the Homer Simpson x-ray on the forensics platform, Dan Castellaneta, the voice of Homer Simpson has a cameo at the start as officer Novarro. (00:02:40)
The Teacher in the Books - S10-E12
Trivia: This episode heavily features the fact Dr. Brennan is now on Twitter. During the original run of the show, there was an active Twitter account in the guise of Dr. Brennan. The account features all the tweets and selfies we see Bones post in the episode, and during the airing of new episodes "Dr. Brennan" would be live tweeting about the show. However its unclear if it was Emily Deschanel tweeting or an employee of Fox. The account (which has been inactive since 2016) is viewable here https://mobile.twitter.com/DrBrennan?lang=en.
Trivia: In this episode, there is an Agent Oakes played by the actor Morris Chestnut. Morris Chestnut later got his own show where he played a character named Beaumont Rosewood Jr. who is a pathologist. This is set in the same universe as Bones because one of Dr. Brennan's interns, Daisy Wick, appears in Rosewood and mentions Dr. Brennan by name.
Answer: Since the palatine bone is a bone that helps form the mouth it has a lot to do with speaking. The shape of it differs a lot depending on your ethnic background. I would guess that they, in the show, meant that the person's bone tells that they were Japanese and that it was "made for the purpose of speaking Japanese." That's what I'd assume anyway. I've studied molecular biology though, so I'm not an expert on bones.
