A BlackComedy set during TheTroubles by [[Creator/MartinMcDonagh Martin [=McDonagh=]]], author of ''InBruges''. It tells the story of insane INLA member Padraic who returns home to sleepy little Inishmore to check on the welfare of his beloved cat, Wee Thomas. Wee Thomas is, in addition to topping the list of things which will make Padraic go on a murderous rampage, Padraic's best friend in the world for fifteen years. Wee Thomas has also just met an unfortunate end through mysterious, but violent circumstances. So naturally, [[HilarityEnsues Carnage Ensues]]. What follows is a superbly hilarious and violent comedy.

!! Contains examples of:
* ACupAngst: Mairead.
* AxCrazy: Padraic and to a lesser extent Mairead
* BlackAndGreyMorality: Running headlong into BlackAndBlackMorality.
* BloodyHilarious: You may find yourself watching the second half of Act II through your fingers while laughing nervously the entire time
* BritishAccents: The [=INLA=] are stated in the script to have Northern Irish accents, to contrast with the rest of the cast's West Coast Irish accent. Of course, how clearly this comes across varies between productions.
* CleanupCrew: Danny and David are roped into cleanup duty once Paidrac has finished with what's left of the INLA. It's a lot to clean up.
* ClusterFBomb: Only the word used here is "feck."
* ColdBloodedTorture: Several instances conducted by Padraic
* DeadPetSketch: Specifically, Dead Cat. ''Extra'' specifically, Wee Thomas.
* DeadpanSnarker: When Davey and Donny aren't afraid for their lives, they can snark with the best of them. For example: [[spoiler: Padraic and Mairead will be married -- when Ireland is free! Says Davey, "That'll be a feckin' long engagement."]]
* [[spoiler: DownerEnding]]
* EvenEvilHasStandards: Kind of subverted, in that while being against selling drugs to children is a typical villain PetTheDog, Padraic is only angry when drugs are sold to ''Catholics''; he has no problem with them being sold to Protestants.
** To the extent the INLA counts as evil, they are a straight example, as they disassociated themselves from Padraic who was much too crazy for them.
** Joey, of Christy's gang, can't get over the fact that he was associatin' with cat batterers.
* EyeScream: One INLA member, Christy, wears an eyepatch, because Padraic previously gouged out his eye- furthering the BlackComedy, he loses the other during the play. Also, when younger, Mairead shot out the eyes of several cows
* {{Gorn}}
* GunsAkimbo: Padraic
* HairTriggerTemper: Padraic
* HoistByHisOwnPetard / KarmicDeath [[spoiler: after painting the stage with blood to avenge his dead cat, Padraic has accidentally killed Mairead's cat. She blows his head off]]
* ImprobableAimingSkills: Mairead's a handy sniper with her air rifle after all that experience shooting cows and her brother. Averted with Padraic, who's a poor shot and prefers to blast people [[ThereIsNoKillLikeOverkill at point-blank range]].
* InLoveWithYourCarnage
* MexicanStandoff
* MistakenIdentity: [[spoiler: The black cat that was killed on the road? A random stray. Wee Thomas is alive and well.]]
* MultipleEndings: The play has two alternate closing lines, depending on whether [[spoiler:the cat playing Wee Thomas eats food that is offered to it or not]].
* NamesToRunAwayFromReallyFast: [[ExactlyWhatItSaysOnTheTin Mad Padraic.]]
* RenegadeSplinterFaction: The [=INLA=] to the [=IRA=], Padraic to the [=INLA=].
* RoaringRampageOfRevenge: To avenge Wee Thomas, Padraic will stop at nothing. Up to and including killing his own father.
* OnlySaneMan: Joey, in Christy's gang. By comparison. Outside of that, Davey and Donny.
* PetTheDog: Well, kind of
* [[spoiler: ShootTheShaggyDog: Nearly everyone is dead, and Mairead is likely to kill her brother and Padraic's father shortly because of their role in the death of her cat. And then it turns out that the [=INLA=] people had only killed a random stray by mistake; Wee Thomas is still alive and well.]]
* ThereIsNoKillLikeOverkill: Padraic shoots ''his cell phone'' when he's mad.
* ATragedyOfImpulsiveness: But who expects restraint when dealing with Mad Padraic?
* {{Tsundere}} / {{Yandere}}: Mairead is very dere for Padraic but tsun towards her brother; on the other hand, she is a {{Yandere}}, to the extent she isn't quite mentally balanced.
* TwoWordsObviousTrope: "One word: [[RenegadeSplinterFaction splinter group!]]"
* WhiteShirtOfDeath: Subverted: Padraic wears a wife-beater when he gets down to torturing, and it gets covered with ''other'' people's blood. [[spoiler: Until he gets killed, and this trope is Double-Subverted.]]
* YourHeadASplode: [[spoiler: Padraic after Mairead shoots him in the head with his two handguns at close range.]]
* YouKeepUsingThatWord:
-->'''Davey''': Them facts are only circumstantial.
-->'''Padraic:''' These guns are only circumstantial, so, and so too your brains'll be only circumstantial as they leave your heads and go skidding up the wall.
