Angela's father is played by ZZ Top member Billy Gibbons, and there have been several indications that the audience is supposed to understand that her father IS Billy Gibbons (albeit a fictional version of Gibbons, since Angela is fictional). Although Angela's dad has never been given a name, before his first appearance Angela told her friends that her father is famous enough that they might recognize him immediately, and during Gibbons' appearances, there have been several references to the music of ZZ Top.

Bones works at the Jeffersonian Institute. There is no such place in Washington, D.C. However, the name is probably a play on the Smithsonian Institute. Shots of the outside of the actual Smithsonian are often used on the show.
Almost every time Booth is in front of the camera, he has on him a watch, his F.B.I. ID, a holstered sidearm, a Zippo lighter, Craps dice, a one hundred dollar poker chip, a floaty pen (the type where a girl's clothes fall off when you turn it upside down), 3"x5" index cards and his light brown sunglasses, and he is wearing a St. Christopher medal. All of these items can be spotted being handled by Booth throughout the series.
Originally, the weight they gave the victim, who was exactly like Brennan, on season six, episode nine, "The Doctor in the Photo", was twenty pounds less than the weight that aired. Emily Deschanel had read the script, and called the other producers, asking them to put the weight closer to reality.
The Royal Diner, where Brennan and Booth (and occasionally the other characters) go to relax after work, really exists in Washington, but the one in New Jersey (on Route 31 North), not the District of Columbia.
The establishing exterior shots of the "Jeffersonian Institute" are filmed on the Exposition Park Rose Gardens side of The Natural History Museum of Los Angeles County.
There have been several references to Agent Seeley Booth being a "direct descendant" of John Wilkes Booth. In reality, is is highly unlikely that John Wilkes Booth had any direct descendants. As the assassin of Abraham Lincoln, and the first assassin of any U.S. President, John Wilkes Booth's life history has been exhaustively scrutinized by generations of historical scholars, and there is absolutely no evidence that he ever married or fathered any children, legitimate or illegitimate. Several of John Wilkes Booth's brothers and sisters did have children, but in genealogical terms, to be a direct descendant John Wilkes Booth, Seeley Booth would have to be descended from a child of his, and not just a niece or nephew.
Angela Montenegro spoke the first line of the series, and Temperance Brennan spoke the last.
Season seven contains a reduced order of thirteen episodes to accommodate Emily Deschanel's pregnancy. FOX ordered an additional four episodes that were produced during the seventh season but aired during the first part of season eight.
The first character that appeared in the pilot episode was Angela Montenegro (Michaela Conlin).
As of season twelve, only two shots in the opening title sequence have remained the same throughout the series: the opening shot of the skeleton, and the final shot of Booth and Brennan in Limbo closing a drawer full of remains.
As a Pennsylvania native, Agent Booth (David Borenaz) is a fan of the Steelers and the Flyers.
Out of the twelve rotating interns on the show, eight received their doctorate: Zack Addy, Clark Edison, Arastoo Vaziri, Oliver Wells, Rodolfo Fuentes, Colin Fisher, Douglas Filmore (Forensic Podiatrist), and most recently, Daisy Wick.
Daisy Wick is the name of one of the secondary characters. Daisy Zick is the name of a real-life murder victim from Battle Creek, Michigan in 1963. The crime remains unsolved.

Carla Gallo (Daisy Wick) and Joel David Moore (Colin Fisher) appeared on House (2004) season three, episode nineteen, "Act Your Age".
Freddie Prinze, Jr., who guest starred for two episodes in season nine, is married to Sarah Michelle Gellar. David Boreanez played Angel alongside Gellar in Buffy the Vampire Slayer (1997).
Up to season three, Special Agent Seeley Booth has handled a Glock 17, a .357 Magnum, a two-tone Smith & Wesson Sigma (commonly misidentified as a Glock, both pistols look and function nearly identical, however Glock does not produce two-toned pistols), and a Tokyo Marui Hi-Capa 5.1 (Airsoft replica) with a tactical flashlight attachment, along with a Colt .22 back-up weapon. While Dr. Temperance Brennan has handled a Colt .22 in the pilot episode, where she shot a suspect, as well as on several occasions to back-up Agent Booth, a very large Smith & Wesson M500 .50 caliber revolver in season two, and Booth's Tokyo Marui Hi-Capa 5.1 Airsoft Replica when she shot Booth's stalker.
The Jeffersonian Institute is a thinly-veiled allusion to the Smithsonian Institute.
