A Black Comedy set during The Troubles by Martin McDonagh, author of In Bruges. 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, Carnage Ensues. What follows is a superbly hilarious and violent comedy.
Bloody Hilarious: You may find yourself watching the second half of Act II through your fingers while laughing nervously the entire time
British Accents: 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.
Cleanup Crew: 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.
Deadpan Snarker: When Davey and Donny aren't afraid for their lives, they can snark with the best of them. For example: Padraic and Mairead will be married — when Ireland is free! Says Davey, "That'll be a feckin' long engagement."
Even Evil Has Standards: Kind of subverted, in that while being against selling drugs to children is a typical villain Pet the Dog, 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.
In a more meta sense, the entire play could be considered a deconstruction of the concept, as every cat lover, with the possible exception of Donny, is portrayed as a complete hypocrite for feeling horror at doing to a cat what they have done to their fellow human beings without hesitation.
Eye Scream: One INLA member, Christy, wears an eyepatch, because Padraic previously gouged out his eye- furthering the Black Comedy, he loses the other during the play. Also, when younger, Mairead shot out the eyes of several cows
Shoot the Shaggy Dog: 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.
