Narm/Theatre

Examples of in  include:

""Now I am dead, now I am fled, my soul is in the sky...""
 * When Cirque Du Soleil debuted KA in 2005, the aftermath of the Battlefield scene had  crying in pain. Audiences laughed at the crying in what was supposed to be a sad scene, so this was dialed back.
 * Saltimbanco's climatic bungee act would be gorgeous if the singer didn't just...sit there and sing while watching the act.
 * Zarkana's baby funeral scene. "Welcome to my funeral, please don't scream..." Audiences find it hard to take seriously and have reportedly mocked it walking out of the show.
 * Older Than Steam: Parodied in the play within a play in Shakespeare's A Midsummer Night's Dream. It's narm In-Universe.

""My leg is cut in two.""
 * Essentially the entirety of that play was meant to be narm through terribad acting.
 * The last few scenes of Othello are ruined by lines like "I am maimed for ever" and "O heavens forfend us!" The latter is possible to say dramatically - but not in unison with somebody else, which is how it's supposed to be said.
 * Iago has the line, "Drown thyself? Drown cats and blind puppies!" Narm is combined with Kick the Dog -- and the dog still got a respectable kick. Shakespeare, you Magnificent Bastard...

"Young Macduff: "Thou liest, shag-haired villain!" Murderer: "What? You egg!""
 * Also in the end of Othello: Desdemona uttering a Final Speech after being suffocated. Suffocation kills you because of lack of air. Air is what you use to speak, Shakespeare.
 * Better in the opera Otello, when she has an entire aria.
 * The conventions of theater might mean that Desdemona's final speech should be taken as an internal monologue and not spoken dialogue. Shakespeare's characters love thinking out loud, and not every instance of that should be interpreted as literal speaking. Still, it's all too easy to interpret it that way...
 * Almost everything Gratiano says in that scene is obvious. For instance, he says, "He's gone, but his wife's killed" to describe an event that happened approximately one second ago in front of everyone.
 * Othello himself mars an otherwise magnificent speech in this scene with "Here is my journey's end, here is my butt..."
 * Some of the deaths in Macbeth. Particularly "Fly, good Fleance, fly, fly, fly!"

""O pardon me, thou bleeding piece of earth...""
 * This is actually a brilliant insult, and one I use all the time. It tends to give people pause.
 * Parodied in Horrible Histories, where the assassin says, "You've done it now, sonny! I happen to be very sensitive about my shag-hair!"
 * 'He has killed me, Mother.' No shit.
 * When the witches greet one another in an early scene and ask where they've been, one replies, "Killing swine." Now, while it was widely believed in Jacobean England that witches travelled the land slaying livestock, there's something about the bluntness of this line that makes it ridiculous.
 * From Julius Caesar, Mark Antony's famous "Dogs of War" soliloquy:

"Student reading Marcellus's part: (awkwardly) Holla, Bernardo! Student reading Bernardo's part: (over-the-top ebonic tone) Say whaaaaat?"
 * This can evoke the image of Caesar as a human-shaped pile of dirt oozing blood.
 * Julius Caesar also features Cassius, who, upon hearing that it looks like the battle is going badly for his friend Titinius down the hill, kills himself. Titinius enters immediately afterward, perfectly fine. It's hard to summon much pathos for a death that could have been averted by waiting thirty seconds.
 * Titinius (or some soldier) immediately kills himself out of sorrow for his beloved commander Cassius. Like Hamlet, Julius Caesar is overly scrupulous about obeying the idea that tragedy means "everyone's dead by the end of the play".
 * Paris says "Oh, I am slain" upon getting stabbed by Romeo in Romeo and Juliet. It's not easy to say in a way anyone can take seriously.
 * Have a Gay Old Time is the cause of quite a bit of Shakespearian Narm. Just try to take Lord Capulet seriously after he calls Mercutio "You saucy boy!"
 * All the 'what, ho's in Romeo and Juliet because of the modern usage of "ho." Especially in English class when read stiffly by students.
 * "O, I am slain!" is uttered by Polonius in Hamlet.
 * The final scene of Hamlet features "I am poison'd."
 * This made reading Hamlet in English class a bit more interesting:

""O would mine eyeballs were to bullets turned, That I in rage might shoot them at your faces!""
 * Many of the Shakespearean examples are in the plays because they announce deaths and, without them, either the actors wouldn't know when to die or the audience in the nosebleed seats wouldn't know if someone had truly died. (That goes for the broken leg as well.)
 * Early Shakespeare has some truly beautiful Narm. In Henry VI Part 1, for instance, there is this hilarious line:

""Titus, this is your daughter!" "Why, Marcus, so she is.""
 * The scene in Titus Andronicus in which Titus is presented his daughter, who had previously been raped and had her hands and tongue cut off/out:

""Oh, I am struck deep with a mortal blow!""
 * And then there's perhaps the most infamous stage direction in all of theater, from The Winters Tale: "O I am gone for ever!" Exit, Pursued by a Bear. The bear is not mentioned at all in the prior speech and just comes out of nowhere. This troper's Shakespeare class erupted in laughter for quite some time after discussing this line, despite it being the death of a character and a fairly important turning point in the play.
 * For modern audiences, Aeschylus' play Agamemnon features a particularly hilarious bit of Narm. While being murdered offstage, the title character delivers this line:

""Oh! Yet again, a second time I am struck!""
 * And then, a few moments later:

""With this switch, for example?""
 * How many mortal blows can a fella get?
 * Come on, it's just a flesh wound!
 * Oedipus the King:
 * Upon the revelation that Oedipus is her son, Iocaste immediately leaves the room. A servant walks in shortly afterward to report that the queen has committed suicide. You may or may not find the abruptness of all this hilarious.
 * I KILLED THEM AAAAALLLLL!!!!! AAAAAAAAARARARAAAAGGGHHHHH!!!! AAAAARRRRRRAAAAAAGGGGHH!!! RAAAAAAGH... aaah....
 * An earlier scene also has Tiresias giving his signature warning to Oedipus while falling down and flopping around on the ground as though spontaneously getting heart attacks. The Chorus has to regularly push him back up, almost to the point of playing catch with him, and the fact that he's been made to look like some tremendous ghostly bird does not help.
 * Spring Awakening has the beating scene, which depending on how it's played, ends up being a Tear Jerker or terrible, terrible narm. Wendla giving Melchior a branch that she found on the ground and wants to be beaten with is a little much to take seriously.
