THE RULE OF THREE'S.....

is a principle in English writing that suggests that things that come in threes are inherently funnier, more satisfying, or more effective than other numbers of things. From slogans ("Go, fight, win!") to films, many things are structured in threes. There were three musketeers, three little pigs, three billy goats Gruff, Goldilocks and the three bears, and Three Stooges.

A series of three is often used to create a progression in which the tension is created, then built up, and finally released. Similarly, adjectives are often grouped together in threes in order to emphasize an idea.
