CONTRADICTION, a set of incompatible premises. Trying to reconcile such a set may result in two or more parts canceling each other out of existence (if properly arranged), interacting with destructive force, joining to create one or more completely different entities, or any of these results in combination.
An example of a contradiction is Broadway Butchery, a play about New York City's Meatpacking District, composed by Raylenette Young of Boise, Idaho and considered by many to be a masterpiece of disinformation. Based on a dream which was inspired by a help-wanted posting in the Idaho Statesman, it is considered both the worst and best theatre play ever written, with both the shortest and longest runs in the twentieth century. The public debut was canceled after one performance due to the disruptive protests of animal-rights groups, who were convinced that cruelty was somehow involved although no living beings took part in the show. However, it remains an underground favorite to the present day, with many repeat attendees forming discussion groups dedicated to sorting out the play's main premise.
Analyses of extradimensional and other possibilities for Broadway Butchery's alternate view of geography are regularly written as a study exercise in city planning courses. These occasionally make their way into official documents, causing some construction projects to have to be demolished and restarted multiple times after impossibilities are attempted.
