If the facts are against you, pound on the law. If the law is against you, pound on the facts. And if both are against you, pound on the table!
— Legal aphorism
The case is going against the defendant when suddenly, the defense attorney starts making penguin noises, discussing his sex life with The Judge, pulling vegetables out from under the defendant's chair, or calls the witness's pet parrot to the stand to testify.
The more desperate the case, the more likely the defense attorney uses such antics.
Perhaps he's stalling for time while an associate tries to find the evidence that will show who the real killer is, or maybe he's finally just flipped under the strain of the case.
Either way, expect him to be allowed to go on making a mockery of the legal system for far longer than any reasonable Judge in Real Life would allow without having him jailed for contempt. To say nothing of the high chance he would be severely disciplined if not disbarred as soon as the nearest Bar Association ethics panel heard about it. Expect The Judge to tell them they're "on thin ice" and "looking at contempt" if they don't get to the point.
Often, this antic will result in a Penultimate Outburst.
Typical Courtroom Antics:
Gintama episode 95 shouts out to Ace Attorney series, so naturally plenty of courtroom antics ensue, including but not limited to watching porn submitted as evidences during trial and having the judge abuse his power to rewind his favorite scenes in slow motion. It has to be seen to be believed.
The Smurfs: After Smurfette casually mentions that Gargamel made her, Papa immediately has her arrested and holds a trial, with Brainy as the prosecutor and Jokey defending her. However, his attempts to have a fair trial keep going Off the Rails, as none of the smurfs want to testify against her, Brainy's attempts to take his job seriously keep getting undermined, and Jokey ultimately accuses Papa of being the one really responsible for what happened.
In The Kentucky Fried Movie, a court skit features a prosecutor who pulls out a large, floppy dildo and waves it threateningly at a witness, inquiring "Are you aware of the penal codes in this state?"
Chicago: This is Billy Flynn's entire law practice. Courtroom antics, press conference antics, and probably an example on every sub-page of this index.
Billy: As long you keep them way off-balance They'll never spot, you got no talents Razzle-Dazzle 'em And they'll never catch wise.
Duck Soup has a version in which the Marx Brothers are performing courtroom antics not to prevent/assure convictions, but simply because their characters are...well...whotheyare. Cases in point: offering the witness bets on whether there's a conviction; objecting on the grounds of "I couldn't think of anything else to say"; sustaining objections on the grounds of "I couldn't think of anything else to say either"; and a pun or two.
Not expected or intended, but deliberately played on: in The Dark Knight, an accused gangster tries to shoot Harvey Dent in the middle of the trial. Dent promptly delivers a cross to his face and disarms him, stunning the entire court. When the judge calls for a recess, Dent hams it up: "Your honor, I'm not done yet". A straight version happens later in the movie, when Dent intends to try most of the Mafia roll call (549 criminals) in one sitting. We get a hilarious scene where the judge reads off the list of transgressions, then asks "How do the defendants plead?" We change to the courtroom, packed with mobsters and their attorneys, and all of the attorneys jostle above each other trying to be heard while the stenographer drops his hands, confused.
The Judd Nelson vehicle "From The Hip" showed future Ally McBeal creator David E. Kelley's penchant for this trope.
Fatal Instinct. Both the prosecution and the defense indulge in these tactics during Lana Ravine's trial.
Parodied to the hilt in the Woody Allen film Bananas. Among his other antics includes Woody Allen's character conducting his own defense, with results in cross-examining himself as a hostile witness.
The prosecutor in 1951's A Place In The Sun (loosely based on a true story) uses this tactic to intimidate the defendant as well as to impress on the jury the violence of the crime. The defendant was accused of drowning his fiancee, so the prosecutor brought in the boat they had been in, stood in it, and proceeded to loudly and violently break an oar against the side to demonstrate how the defendant supposedly hit the victim in the head before drowning her (the film leaves it up in the air whether or not the drowning was intentional, but he never hit her).
Amanda Bonner in Adams Rib practically turns the courtroom into a circus.
A number of these occur inThe Three Stooges short "Disorder In the Court", which is to be expected when characters like the stooges enter a courtroom. While trying to clear an innocent woman of murder, they proceed to re-enact the events of the night of the murder, including an unrelated musical sequence, get perhaps a little too realistic when re-enacting the murder itself (no one dies, but Larry is subject to a bit of abuse), and chase a parrot around the courtroom with a fire hose.
Justified in Miracle on 34th Street in that the proceeding is a judicial inquiry, not a criminal trial, and Judge Harper was fearful of the political fallout of committing Kris Kringle to a mental institution, so he gave Fred Gailey considerable leeway to allow him to make a reasonable argument to let Kris go.
In Serial Mom, a character pulls down a not guilty verdict by a series of ridiculous antics. Getting away with them requires a practically blind judge and DA.note The defendant booted her attorney when he tried to enter an insanity plea.
The People Vs Larry Flynt shows a few of the antics Flynt performed in his many lawsuits. Given it's based on true facts, no wonder Columbia Pictures didn't invite him for the Academy Awards afterwards (his on-screen portrayer Woody Harrelson had to give his agent's seat).
Invoked in the Forgotten Realms novel Tantras. Storm Silverhand, the prosecutor against the protagonists who stand accused of murdering Elminster, makes an absolute mockery of the court. She uses horribly leading questions, badgering of witnesses, whipping the audience into am emotional frenzy with screamed accusations, and claims the defense attorney has been magically charmed by his clients when he protests this behavior. In the end her behavior is not only allowed, she actually wins the case without a shred of solid evidence.
The Discworld novel Making Money has a trial in which our hero, Moist von Lipwig, currently acting chairman of the bank, is on trial for the unexplained disappearance of nearly ten tons of gold. He's very nervous about a former accomplice of his threatening to reveal that he is, in fact, a former con artist who had been hanged under an assumed name, and has a slightly guilty conscience as he submits to questioning, when he sees a small dog (the actual chairman) wander in while sitting down and wagging its tail. These are both happening at once because the dog is holding in its mouth its favorite toy - a huge chewy vibrator - which has turned itself on and whose vibrations are propelling the sitting dog backwards across the courtroom floor and out of sight while everybody tries desperately not to notice and offend the Patrician. Lipwig reasons that a world in which this can actually happen in the middle of a court is a world which can handle him acting as chairman of a bank, and proceeds to confess everything about his backstory.
The murder trial in Little Fuzzy, starting even before the trial begins, with two murder cases being combined into a single trial, the appointment of the defense attorneys as special prosecutors, and key witnesses being seized as "evidence." It goes on to mutate from a civilian trial into a court-martial and an academic seminar, with two flavors of surprise witnesses, and the continued prosecution of a dead man after one of the defendants commits suicide. And there are in-universe precedents for most of this: "You could find a precedent for almost anything in colonial law."
John Scalzi's reboot novel Fuzzy Nation has a much more cynical version; Jack Holloway is a lawyer who was disbarred when he punched his client in the middle of a trial. He claims to have done it in a fit of outrage at what the guy was trying to get away with, but it is strongly implied that he was actually paid a huge sum to do it, in order to force a mistrial.
In Angels sole courtroom episode, Gunn defended an arms dealer who threatened to detonate a bio-weapon over Los Angeles if he was found guilty. Gunn's unique strategy was to ask the judge to recuse herself, as she owned stock in a shell company owned by the defendant. Check and mate.
Law & Order had Jack McCoy go off on an increasingly hostile rant made up mostly of revealing evidence that was inadmissible so he could get a mistrial and try the case again if/when the body was found. He did get in trouble for it (contempt of court) so it was a bit of a falling on his sword moment.
An episode of Law & Order: Special Victims Unit had the prosecution trot out a child witness (whom they had no intention of actually forcing to testify) for the sole purpose of having him dramatically react to the defendant's (his own father) presence. The judge let it fly without so much as a jury instruction to disregard.
In a completely opposite and somewhat deconstructed example, a judge orders a child witness in a rape case to testify in person. The prosecutors ask for, and are denied, the option of having the girl testify via closed-circuit television in order to spare her from being in the same room as the accused. Although they tell the girl to keep her eyes forward and not look around when she enters the courtroom to avoid contact with her attacker as much as possible, when she enters, she glances up and sees the defendant seated at his table. She stops and stares for several moments before the prosecutor withdraws any questions she has and ushers the girl away. Immediately after, the defense accuses her of orchestrating a Courtroom Antic; by letting the girl come out and stare at the defendant, she gives the jury the impression of recognition and therefore guilt, which they feel counts as testimony, while denying the defense the opportunity to cross-examine.
An episode of CI put more work into this. It was Detective Goren rather than the ADA who pulled this. He played the fool in order to keep the antic going longer and ended up getting thrown off the stand anyway.
The Dukes of Hazzard: The Season 4 episode "Coltrane vs. Duke" featured Rosco suing the Dukes for the mortgage to the farm (valued at $50,000) after claiming to have suffered serious injuries in his latest pursuit of the Duke boys. Of course, there's plenty of Courtroom Antics on hand, most notably Boss Hogg hiring one of his many corrupt associates as a surprise witness ... a doctor who can prove that Rosco's "injuries" were directly the pursuit of crashing his squad car when Bo and Luke refused to stop for Rosco. And yes, Rosco overdramatizes his injuries as well, lending to plenty of the show's humor. In the end, the Dukes have plenty of aces up their sleeve to expose Rosco's injuries as fake.
A rather amusing version from The 10th Kingdom has Virginia exclaim, after Wolf has practically incriminated himself while being grilled by the Judge, "Your Honor, my client is suffering from post-menstrual tension!". Wolf's memorably existential self-defense: "Ohhhh, I'm twisting everything I'm saying!"
The point of This Is Wonderland. Courtrooms have seen arguments (not always in English), violence, spoken-word poetry, a fake heart attack, car theft from the courthouse's parking lot, mixups with defendant's names, shouts of ?Boo!?, the outbreak of true love, and the occasional Freudian Slip. Judge Maxwell Frasier, who has been known to threaten arrest for this sort of behavior out of anyone other than himself, would often yawn loudly while people he didn't like were talking, call a recess because he was hungry/bored, or go crazy and scream.
Inverted in an episode of Frasier: a mental competency hearing for a wealthy old man, in which Frasier is appearing for the defense, is going very well for Frasier, who is acting like a consummate professional — until the defendant's senility kicks in and he chooses that moment to start acting like a train conductor, including punching 'tickets' (the judge's notes and Frasier's tie) and announcing arrivals. However, a milder example of this trope played straight appears with Niles, who is appearing for the plaintiff and, as the proceedings are being televised, is playing up to the cameras outrageously. The judge is still quick to tell him off about it, however.
In an episode of Blackadder Goes Forth, George, as a defense lawyer, calls the prosecution lawyer as a witness.
George: Do you believe Captain Blackadder is the sort of man who habitually disobeys orders?
George: Oh. I was rather hoping you'd say "no".
The incompetence of George's Courtroom Antics doesn't make much difference though; given that he has already been found guilty of wasting the court's time for bothering with a defence at all and Darling later calls the judge as a witness (with a lot more success, since he's also the wronged party), this is Kangaroo Court at its most blatant.
The Witchsmeller Pursuivant episode of series one has the Witchsmeller bring in Edmund's horse, Black Satin and first decide its silence means it has something to hide, and then when it says "Neigh" he doesn't believe a word of it, bring in a dog which he claims is Edmund's son, and accuse Baldrick of being a witch for saying that carrots don't grow on trees. Maybe it's just because he was playing a sick man, but BRIAN BLESSED isn't the biggest ham in that episode.
LOST: Kate's trial in "Eggtown" hinges partly on Surprise Witness (Jack) and more on Surprise Lack-of-Witness (when Kate's mother is not available to testify).
Night Court practically runs on this trope, from the Judge of all people.
In the Red Dwarf episode "Justice", Rimmer is arrested for the murder of the entire crew of Red Dwarf barring Lister (including himself, if you think about it. Kryten is his lawyer at the subsequent trial, and his defense involves proving Rimmer is too stupid and incompetent to hold enough responbility for any deaths. Rimmer helps in this regard by OBJECTING to his own defense.
It Makes Sense in Context, the evidence against Rimmer is that he truely believes he's responsible according to a mind scan; the defence is showing both that Rimmer is the kind of person who thinks it's his fault even when it isn't and he couldn't actually be responsible.
Hardison's performance as a lawyer on Leverage was full of this. He started by bringing in a massive amount of information so boring and irrelevant that the judge was falling asleep, when by that point she should definitely have been demanding an actual justification for why it was important. Then he discredited his opposition's expert witness by bringing up the fact that he was on the no-fly list, which he only knew by hacking into their database and so had no proof of, and claiming that if the government didn't trust him to fly how could they trust his testimony. The judge ignored their objection and didn't give so much as a Disregard That Statement.
Bones occasionally devolves into this when the characters have to actually get convicted. Notable events include Caroline objecting because she found something offensive, and Angela taking the First Amendment "which protects freedom of assembly, and that includes friendship." In the last case, though, she was actually jailed for contempt of court.
In an episode of Star Trek: Voyager, Q, acting as an advocate for the Q Continuum, is called to the stand by the advocate of another Q seeking asylum. The solution, Q puts himself in two places at once and commences to cross-examine himself.
One House episode sees Dr. House in court for violating a Do Not Resuscitate order. His lawyer tries using a clever, albeit spurious legal ploy, which would be promptly shot down by the other party's lawyer. House stands up and explains that, while it's utterly irrelevant to the case at hand, he suspects the judge has a medical condition he should get checked for ASAP; which distracts the worried judge for the rest of the proceedings, including (presumably) the part where House's legal argument is torn to pieces.
Rumpole of the Bailey: Rumpole has, in extremis, produced the occasional really impressive Courtroom Antic. In "Rumpole and the Last Resort", he secured an adjournment in spite of an unsympathetic judge by collapsing and dying right there in the courtroom. (It was the season finale, too, so we couldn't be entirely sure he hadn't been Killed Off for Real.)
One episode of Farscape has Zhaan framed for murder on Litigara, a planet where 90% of the population are lawyers. Chiana and Rygel defend her, ultimately exposing the true culprit with the "Light of Truth," a burning chair leg. That Pilot was making brighter from orbit.
The title characters of Franklin & Bash frequently employ these — especially Jared Franklin. It's their thing.
One of Jeff's from Community go to strategies. Fails about as often as it works. In Community episode Debate 109 when he uses it during a Debate match his team loses the first round, 50-8 (and the 8 were to Annie).
In Just Cause, Whit gets a possibly senile court-appointed client who refuses to speak except through a dummy. So he calls the dummy to the witness stand.
Sue Thomas: F.B.Eye: In the pilot, Sue, a Deaf woman who reads lips for the FBI, testifies in court about a conversation held in a surveillance video with no sound. The defense attorney calls her accuracy into question, then approaches the bench and tells the judge that Sue could be making things up and is unreliable. Sue, reading his lips, shouts out "I object!" from the witness chair.
In the Doctor Who story The Trial of a Time Lord, the Valeyard altered the video evidence, including the video in the Doctor's defence, to make the Doctor look like a criminal.
In "Heroes" (season 2), a key piece of evidence in the case was a submachine gun that allegedly failed to fire due to a malfunction. Harm proceeded to pick up the gun, which had evidently never been unloaded, and fired it into the ceiling. This did get him an epic ass-chewing, and the judge would continue to hold this against Harm for at least 7 more seasons.
In "Killer Instinct" (season 6), the defendant is a petty officer on an Aircraft Carrier suspected of murdering a subordinate (by throwing overboard at night), because they were incompetent at their jobs. One crucial piece of evidence is not admissible in court because the ship's CO did not have probable cause for issuing a search warrant, and this necessitates a different strategy from the prosecution. Harm does the standard Perry Mason Method, knowing beforehand that the defendant will not fall into the trap and make him overconfident. And when Bud later has his turn to question him, he begins by asking the defendant several questions that Harm had asked earlier, then proceeds to make several other basic errors before dropping his notes in mid-question, and finally drives the pedantic defendant into a rage, before revealing that he was Obfuscating Stupidity and it was all part of a plan.
Petty Officer Duell: Some people donít belong in the United States Navy.
Lieutenant Roberts: No, but the Navy wonít kill them.
Defense attorney Henry Drummond calls the prosecutor to the witness stand in Inherit the Wind. This actually ends up becoming Drummond's Crowning Moment of Awesome. This was based on the real cross-examination of William Jennings Bryan by Clarence Darrow from the Scopes Monkey Trial in 1925.
Which kind of fails, as Courtroom Antics are generally for the benefit of the jury. In the Scopes trial there was no jury. It's the reason it never made it to the Supreme Court. The judgment was overturned because the fine assessed was an amount that required a jury. His conviction was overturned, so there was nothing to appeal. The case was, wisely, never refiled.
Sometimes antics are for the jury, and sometimes they're for the press. Darrow got exactly the publicity he wanted when he cross-examined Bryan, in newspapers across the country and in history books.
The entirety of Trial By Jury which involves, among other things, the court usher telling the jury to ignore what the defendant has to say and the judge marrying the plaintiff at the end.
In Theatre/Chicago, Billy Flynn the defense lawyer is an expert at this. He likens the court to a three-ringed circus, where your job isn't to tell the truth, but to put on a good show.
Give 'em the old razzle dazzle
How can they see with sequins in their eyes?
The point and appeal of the Ace Attorney series is probably best summed up by this trope. The first game alone has the protagonist cross-examining a parrot and waving a metal detector around the courtroom, and by the final case of the Phoenix arc you're cross-examining a dead person channeled by your assistant.
There's a twist in that Phoenix himself (a defense attorney) maintains a level of professionalism, but many of the prosecutors do not. In the first game, Manfred von Karma practically intimidates the judge into letting him run the courtroom; in the second game, von Karma's younger daughter Franziska (also a prosecutor) tries to cow the judge, the witnesses, and the defense by smacking them with her whip, even going so far as to whip poor Phoenix unconscious after losing case 2 (See here for an excellent example of Franziska's whipping-ness); in the third game, prosecutor Godot throws his scalding hot coffee across the room in a fit of pique several times. All of Godot's responses tend to consist of bizarre philosophical tangents, most of them about coffee. Also, whenever the judge mentions that he's ready to render judgment or something like that, Godot cuts him off with 'I'll be the one to pass judgment, old man!'; and in the fifth game, prosecutor Blackquill sends his bird (a hawk) to attack you in the middle of a trial, not to mention showing off his sword-hand skills with that feather that was just two inches from Wright's face... Yeah. Ironically enough, Phoenix himself often gets berated by the judge for much less.
In Mass Effect 2, during Tali's treason trial, one of the options Shepard has to exonerate her is to rally the courtroom crowd against the Admiralty Board, exposing their political maneuvering and bringing both Veetor and Kal'Reegar to her support, culminating in loudly denouncing the Admirals, Kal'Reegar declaring that "you assholes" will have to exile him too, and the crowd getting noisy enough that they're about to start an enviro-suited riot. Normally this wouldn't work in a more formal courtroom for any species other than quarians, but the close-knit nature of quarian society means that the trial is not only fairly informal to start with, but that the generally loud and flagrant disapproval of so many people has a much greater effect on the quarian Admirals than it would in any other courtroom.
In that trial, the only two 'legal' responses appear to be giving the evidence and breaking Tali's heart, or withholding it, allowing her to be exiled but at least with the knowledge that they won't know what her father did. Shepard actually has as many as three third options, and they're all antics - rather, one antic. Rallying the crowd is above, but Shepard can also personally shout down the Admiralty Board, leaning more towards viciously berating them or extolling Tali's heroism. Either way, they initially protest the antic, but as the crowd starts shouting they are shamed into dropping the charges.
This behavior is actually subverted in the first game. In a desperate attempt to expose Saren's crimes, Captain Anderson tries to submit a dream into evidence. This makes some sense in context, since the dream is a prophetic vision. However, Anderson has no way of proving this, and if he could, the dream's content has nothing that can implicate Saren. Anderson is immediately ridiculed and punished for this behavior by being Kicked Upstairs (in Anderson's defense, he has a very bad history with Saren, and it's clear he was desperate and wasn't thinking straight at the time). When Saren is exposed, it's done with proper evidence, a voice recording that clearly proves that he was heavily involved. ("Eden Prime was a major victory.")
Antics In this strip, Fletcher decides to represent himself in court, and makes a surprising defense statement
Duckman: Duckman resorts to desperate measures such as accusing a witness of being Japanese and acting generally ridiculous. "A-HA! You ASSUME! But everyone knows that when you ASSUME... (pulls out a chalkboard) uh... wait, there's some kinda trick to this..." Eventually his nonstop insanity causes the real culprit, King Chicken, to confess rather than have to listen to him any longer. What makes this particularly funny was the fact that Cornfed actually got Duckman acquitted before he used these tactics.
The trial is presided over by the honorable Judge Reinhold, and he lets Randal get away with his nonsense through open bias.
Randal calls a series of "surprise witnesses" during Dante's trial. All of the witnesses are directors of movies Randal didn't like, and he demands refunds from each of them. After he's finished, the witnesses leave, without ever saying a single word that has to do with the trial's actual proceedings. He also calls a girl to the witness stand just to get her phone number.
The prosecuting lawyer has Dante questioned by a pair of giggling girls, and plays the tapes of a completely unrelated prank call made by Jay and Randal.
Subverted on Futurama where increasingly outrageous antics (the DEFENSE calling the JURY as a witness - they are later instructed to "disregard [their] own testimony") and requests ("Your Honor, I know the case is closed and you've rendered your verdict, but I want to testify") are met with the judge simply saying "I'm going to allow this."
Double subverted in the same episode. The judge even says "I'm going to allow this" when the attorneys do things that are completely conventional, such as cross-examining a witness.
On yet another occasion, the Hyperchicken, acting as Fry and Bender's defense attorney, introduces evidence that proves his clients guilty and then moves that he be disbarred for doing so.
Since Defence Counsel must NEVER do this, and leads to a mistrial, and in the United States in any case would lead to a breach of due process, the Hyperchicken was actually a far more brilliant lawyer than everyone gives him credit for.
In any case, it's debatable whether or not you can blame him for the fact that his witness, a surveillance camera, had a memory so fuzzy that he didn't see that Bender and Fry were actually hostages.
And then in the same case, the Hyperchicken convinced his clients to change their plea from innocent to not guilty by reason of insanity mid-trial. When the judge asked if he had any substantiating evidence that his clients were insane, he replied, "Well, for one, they hired me as their defense attorney." It worked.
Parodied on The Simpsons; while stalling for time in Bart's suit against the makers of Itchy and Scratchy, Lionel Hutz decides to call all his surprise witnesses again, to groans from people in the court; the group includes Ralph Wiggum, a Santa Claus in a cast, and Billy & Benny McCrary, the "world's fattest twins."
The permissive judge aspect of this trope was spoofed in another episode, where Bart makes an unusual request of the judge. The judge replies, "Well, it is highly unorthodox...so no!"
And again: "Even though reopening a trial at this point is illegal and grossly unconstitutional, I just can't say no to kids."
In one episode of Rugrats, Angelica sues her parents for feeding her broccoli. Once in court, she instantly wins over the judge, calls her doll Cynthia and her stuffed zebra as witnesses, and the jury awards her all of her parents assets without even deliberating. It turns out that the episode was All Just a Dream of Drew's.
Lampshaded in King of the Hill when Hank is at a workman's comp hearing after being accused of faking a back injury because he was photographed after Yoga cured him. He asks permission to call in a suprise witness (his Yoga instructor, who proceeds to prance around, accuse the officials of having bad energy, and hit on the secretary) leading the chairman to remark that they'd never had anyone call in surprise witnesses before. Played Straight several times with Dale Gribble, who defends himself in a drug case by rejecting the courts authority because the American flag has the wrong trim, convinces Hank to fight his wrongfully incurred bill for renting pornography by accusing a vast artificially intelligent computer network known as "The Beast" of attempting to defraud him, and when representing himself in a case against his cigarette company calls himself to the stand as a witness in a scene that looks like a cross between Perry Mason and Gollum.
Dale: I do not recognize the authority of a court that hangs the gold-fringed flag. A flag with gilded edges is the flag of an admirality court. An admirality court signifies a naval court-martial. I cannot be court-martialled twice. That is all! Furthermore... (bailiff gags him)
Notable that there actually are people who argue that US courts don't have jurisdiction due to flag trim (among other things). No, it doesn't work.
Animaniacs had an episode where Dr. Scratchandsniff gets a parking ticket and the Warners defend him in court to contest. Examples include holding up a badger to the witness and telling another witness that they "shouldn't swear, it's not nice," after having asked if they swear.
An episode of Jimmy Two-Shoes had Jimmy being tried for trying to fake the Miseryville version of the Tooth Fairy, with this as the result.
Jack Thompson, aside from his video game-related shenanigans, is also someone who once introduced dozens of pages of gay porn into evidence—pages which were then put directly into the evidence database. Subverted in that he actually got disbarred for it.
The above example in the Scopes trial (prosecutor called to the witness stand by defense) is not unique. It happened to prosecutor Vincent Bugliosi in the Manson trial (this was deemed justified by Bugliosi having also been very involved in the investigation of the case).
A lot of courtroom tropes from before the 1980's originated in the trial of Bruno Hauptman who was accused of kidnapping and murdering Charles Lindbergh, Jr. The defense was paid by William Randolph Hearst in exchange for working half-heartedly and betraying his client's confidences (the lawyer also received nightly visits of NYC showgirls with champagne, courtesy of Mr. Hearst), a whole string of surprise witnesses who tended to contradict their own testimony and their statements to police, women fainting after pointing to Hauptman, and a judge who did absolutely nothing to rein in the prosecutor's (who was also the Attorney General of New Jersey) excesses and violations of procedure (both wanted to use the case to advance their political careers).
The Trial of the Chicago Seven. Several scenes from the transcripts from that infamous trial, including the defendants wearing judges' robes (with Chicago police uniforms underneath) to mock what they believed was a biased court, were dramatized in the film Steal This Movie, among other works. The defense also called various countercultural icons of the time as witnesses, including Phil Ochs, Arlow Guthrie, Judy Collins, Norman Mailer, Timothy Leary, and Jesse Jackson.
A big part of the reason Saddam Hussein's trial went on for as long as it did was because he would always delay the proceedings with rants and the like. Since he was already a lock for either life in prison or death (the trial was basically to decide which he would get), what's the worst the judge could do? Throw him in prison?
John Allen Muhammad, one half of the infamous Beltway Sniper duo, attempted to represent himself during his first trial. Immediately after delivering his opening argument, during which he did such things as attempt to call former President Bill Clinton to the stand, he decided to avail himself of his court-appointed counsel instead, not that it helped. Whether Muhammad was engaging in this trope as part of some larger gambit, or was just batshit insane, is open for debate.
Attempted during former Governor Rod Blagojevich's corruption trial for attempting to sell Barack Obama's Senate seat when he became President. Despite the judge already having ruled that the minutiae of the FBI wiretaps was irrelevant, the defense attorney asked the very first witness several times how many hours of wiretap footage they'd collected, trying to plant the suggestion to the jury that what they were allowed to hear was heavily edited to cast his client in the worst possible light. After the third or fourth time, the judge dismissed the jury for a while and lambasted the defense for trying to play a Chewbacca Defense.
OJ Simpson's murder trial may as well be called Courtroom Antics On Drugs. The Other Wiki has an exhaustive summary. Be dazzled by tropes inverted, invoked, subverted and played straight, with a surprise appearance by Godwin's Law in the final moments. Jurors, prosecutors, detectives, defence attorneys, and witnesses quickly put out memoirs in the wake of the case, and in 2012, the prosecution accused the defence of falsifying evidence (the same charge the defence made against the prosecution at trial), so the fight is still active. Cochan's closing statement is perhaps the most egregious example of this trope and something of a Memetic Mutation.
