The Zeroth Law of Trope Examples

"Shakespeare Did It First!"

He may not have been the Trope Maker or even the Ur Example, but you can bet your bottom dollar that he did it before you! Whatever great invention, character or plot device you come up with, Shakespeare is always the guy who has already done it and done it better than you could ever hope to. Note that he wasn't the first to use a lot of these conventions, however he's the earliest writer most people know who used so many of them.

His fans have been aware of this long before the Internet. Horace Walpole, widely recognized as the inventor of the Gothic Horror genre, proudly admitted he borrowed most of the ingredients for the Gothic recipe from his idol.

Shakespeare was not only the first to use many a trope, but the first troper. That is, the first to comment on it. Some examples:

""He that hath a beard is more than a youth, and he that hath no beard is less than a man;""
 * Badass Beard

- Much Ado About Nothing

""So, oft it chances in particular men, That for some vicious mole of nature in them... Carrying, I say, the stamp of one defect, Being nature's livery, or fortune's star, Their virtues else -- be they as pure as grace, As infinite as man may undergo -- Shall in the general censure take corruption From that particular fault.""
 * Fatal Flaw

- Hamlet

""But this denoted a foregone conclusion: 'Tis a shrewd doubt, though it be but a dream.""
 * Foregone Conclusion: Shakespeare coined the phrase, although he used it to mean the inverse and it got trope decayed ("foregone" means "averted" even today):

- Othello

""Nor do not saw the air too much with your hands, but suit the action to the word, the word to the action.""
 * Hamming It Up:

- Hamlet

""If this were acted upon the stage I would condemn it as an improbable fiction.""
 * Lampshade Hanging:

- Twelfth Night

""Do not infest your mind with beating on The strangeness of this business""
 * MST3K Mantra:

- The Tempest

""Out, damned spot! out, I say!""
 * Naughty Nuns: In Measure for Measure
 * Out, Damned Spot!:

- Macbeth

"Puck: If we shadows have offended / Think but this, and all is mended That you have but slumbered here / While these visions did appear And this weak and idle theme, / no more yielding, but a dream take my hand, if we be friends / and Robin shall restore amends"
 * Prince and Pauper: The Taming of the Shrew used this one almost three centuries before the Trope Namer did.
 * Refuge in Audacity

- A Midsummer Night's Dream

""How many times shall this our lofty scene be acted o'er? In states unborn and accents yet unknown"."
 * Seen It a Million Times:

- Julius Caesar

"Demetrius: Villain, what hast thou done? Aaron: That which thou canst not undo. Chiron: Thou hast undone our mother. Aaron: Villain, I have done thy mother."
 * Show Within a Show: Many times.
 * Sock Puppet: The use of multiple user ID's to pretend to be someone else or create artificial support for one side in a debate is usually associated with the Internet era, but the same trick was used in Julius Caesar Act 1 Scene 2 by creating hardcopy messages "in different hands" (ie: by forging the handwriting to appear to be multiple other people) and physically throwing them through Brutus' window.
 * Spin-Off: The character of Falstaff, from Henry IV parts 1 and 2, was given his own play, at Royal request.
 * Sweet Polly Oliver: The Bard had five plays that made use of this plot - As You Like It, Two Gentlemen of Verona, Twelfth Night, The Merchant of Venice, and Cymbeline - long before the Trope Namer was written. Was pretty easy for a playwright to use this Trope during a time period where female characters were always played by men anyway.
 * Your Mom:

- Titus Andronicus

"Painter: Y'are a dog. Apemantus: Thy mother's of my generation. What's she, if I be a dog?"

- Timon of Athens

Quite possibly the ultimate proof of the truth of this law: Shakespeare has an example of a Sock Puppet in Julius Caesar. Yes, a character uses a made-up persona in a play set in ancient Rome and written in Elizabethan England. It's also used as an early example of Astroturfing.
