In chapter six, Napoleon breaks the Fourth Commandment, which prohibits animals from sleeping in beds. Napoleon ends up sleeping in Mr. Jones's bed in the farmhouse. Later on, Squealer alters the Fourth Commandment by adding the words "with sheets" in order to justify Napoleon's actions.
In chapter ten, Napoleon begins wearing Mr. Jones's clothes and walks upright around the farm in a black coat, ratcatcher breeches, and leather leggings. Napoleon breaks the first three commandments that prohibit the animals from wearing clothes and correctly distinguishing their enemies on two legs from their allies on four legs.
Napoleon and the other pigs also discover a case of whiskey in the basement of the farmhouse and proceed to get drunk. Napoleon ends up breaking the Fifth Commandment, which prohibits animals from drinking alcohol. However, Squealer alters the commandment by adding the words "to excess" at the end of it.
