->'''Otto Palindrome:''' Palindrome here, sir; sorry to disturb you.\\
'''The Head:''' That's alright. I was just, as usual, thinking.\\

'''The Head:''' Don't tell me about headaches, Palindrome.\\
'''Otto Palindrome:''' No sir.\\
'''The Head:''' I wrote the book on headaches!
-->-- ''Series/{{Quark}}'', "Pilot"

A StockPhrase commonly used when a character complains or brags about something, to which another character disregards their comment by saying something around the lines of "Don't tell me about that, I WroteTheBookOnIt!". There are two distinct contexts in which this gets used:

* A character is making a boast about ''their own'' expertise on a subject.
* A character commends someone else for being well-renowned on a given subject.

Generally, the "book" in question is just hyperbole and no such thing was ever published; although this can be parodied if it's claimed that they "''literally'' wrote the book on it".

Common [[Administrivia/TropesAreFlexible variations]] include "X? I'm the king of X!", "I invented X!" and "[[MetaphorIsMyMiddleName X is my middle name!]]" Again, usually hyperbole, [[LiteralMetaphor except when it isn't]].

-->'''Alonzo Hawk:''' Since none of your pitiful excuses for men have enough muscle to move a feeble little old lady off her property, I'll go and do it myself, like I have to everything that's important around here.\\
'''Lawyer:''' Now, Mr. Hawk...\\
'''Alonzo Hawk:''' Oh, shut up! We'll start on Number 1 - Harassment! And I wrote the book on harrassment - We'll shut up her phone, turn off her water; we'll sic the Health & Building inspectors on her, steal her dog.
* From the 1999 film ''Film/TeachingMrsTingle'':
-->'''Leigh Ann Watson:''' I am not scared of you.\\
'''Mrs. Tingle:''' Who do you think you're fooling? You're so scared I can smell it. Your fear is the most predictable thing about you. You've lived your whole life in fear. Terrified of making a mistake; Scared to death you won't get that A, that ticket out. Afraid you'll never escape your mother and her name tag. Or your father who won't return your calls. That's why you shunned Luke and every other boy who has ever tried to put his hands on you. You're afraid of getting that bad seed. Afraid of giving birth to a child you never wanted. A child you could only blame for your own wretched existance. Stuck in a small town with a small name. Destined to become that very thing you despise the most. I know all about it, Leigh Ann. I wrote the book! I know you.
* From the 1989 film ''[[Film/ThePunisher1989 The Punisher]]'':
-->'''Sam Leary:''' So how come you never gave up on Frank Castle, like everybody else did?\\
'''Jake:''' Because I know what it's like to be given up on.\\
'''Sam Leary:''' Who gave up on ''you''?\\
'''Jake:''' Everyone and myself. You know how most cops like to go out for a drink after work? Well, I kept moving on up... to the drink ''before'' work, the drink ''during'' work, and finally the drink ''instead of'' work. It got to be a real problem; nobody wanted to deal with it, least of all me. Before I knew it, I was down to cleaning empty shells off the firing range. Then along came Frank Castle, ex-Marine commando with a shiny new police badge, and a request to learn from the man who wrote the book on busting bad guys: me. He helped me get my act together, and the rest is history.
* From the 1990 film ''Film/TheGrifters'':
-->'''Lilly Dillon:''' You're working some angle, and don't tell me you're not because I wrote the book!
* The "I invented" variation is used in ''[[Film/TheSantaClause The Santa Clause 3]]'':

'''Jack Frost:''' I invented chill!
* Played with in ''Film/{{Patton}}'': General Patton knows that Rommel literally wrote the book on tank warfare, so he reads it and uses that knowledge to [[BatmanGambit predict what Rommel will do]] at their first big showdown.

* In the film of ''Film/LAConfidential'', when Exley and Bud White go to question the DA, at one point he tells them "Don't pull that GoodCopBadCop crap on me, I practically invented it." At that point Exley just lets Bud go into full blown JackBauerInterrogationTechnique. At the end, after the terrified DA has told them everything he knows, Exley sarcastically asks him if that's how he used to do the good cop/bad cop routine.

[[folder:Folklore]]
* An [[http://www.snopes.com/college/admin/textbook.asp urban legend]] tells of a highly respected Criminology instructor with years of experience who taught at a state college for ten years. However, he only had a BA and growing credential inflation forced him to enroll in another college to get a graduate degree and keep his job. On his first day of class, his instructor asked him if he was related to the person who wrote the textbook due to having the same name... only for the "student" to reply that ''he'' wrote the textbook.\\\
Nice story, but impossible, as most graduate programs do not have sitdown classes, and if you could produce a textbook on criminology, you could probably enter that as your thesis and pick up a diploma on your way out.

** In ''Discworld/CarpeJugulum'', when Reverend Oats confronts the Count with passages from the Book of Om, the Count starts quoting the passages back at him, and reveals that he, was involved in writing some sections of the book himself, causing Oats to quite seriously question his faith in the holy text.
* Inverted in ''Literature/HarryPotterAndTheChamberOfSecrets'', when Hagrid complains that Lockhart (who ''did'' write the book on dealing with magical pests[[note]]Although not ''the'' book on magical creatures, [[FantasticBeastsAndWhereToFindThem that was Newt Scamander]].[[/note]]) insisted on giving him advice despite the fact it wasn't anything he didn't know.
* In the first ''Literature/ProtectorOfTheSmall'', [[TheStoic Keladry]] actually grins when she finds out the textbook on Yamani manners being used in her etiquette class was written by her father, the former Yamani ambassador.

* In the second book of ''Literature/TheSecretsOfTheImmortalNicholasFlamel'', Machiavelli uses this. He gets to say not only that he wrote the book, but that he did so four hundred years ago.

'''Captain William T. Riker:''' It's not that simple. This was his crew. He wrote the book on this ship.\\

'''La Forge''': Er, the tank can't withstand that kind of pressure. \\
'''Scotty''': [laughs] Where'd you get that idea? \\
'''La Forge''': What do you mean, where did I get that idea? It's in the impulse engine specifications. \\
'''Scotty''': Regulation 42/15 - Pressure Variances on the IRC Tank Storage? \\
'''La Forge''': Yeah. \\

* From the episode "There Might Be Blood" of ''Series/GossipGirl'':
