Booth quips to Bones "Turns out I'm smarter than a 5th grader". Ty Panitz who plays Booth's son Parker was on the game show "Are you Smarter Than a 5th Grader" as a member of the "class."
When Bones and Booth are in the car talking about equine fetish, Bones says that "Pony fetish has been around since the Greeks." Then she says that "In 16th century Turkey, the king kept stables of pony girls and pony boys." This is erroneous in that Turkey didn't exist until the 20th century and also the preceding Ottoman Empire did not have kings, it had sultans.
