The Simpsons on FOX is the longest running scripted prime time animated series show in television history with the debute over 20 years ago. The American animated sitcom is a satirical parody of a middle class hardworking family lifestyle in the fictional town of Springfield. The Simpsons Movie released in 2007 was also a big hit. Homer, Marge, Bart, Lisa, and Maggie epitomize the american family in a comical setting. Homer’s exclamatory catchphrase “D’oh!” has been adopted into the English language.

Homer, the father, works as a safety inspector at the Springfield Nuclear Power Plant, a position at odds with his careless, buffoonish personality. He is married to Marge Simpson, a stereotypical American housewife and mother. They have three children: Bart, a ten-year-old troublemaker; Lisa, a precocious eight-year-old activist; and Maggie, the baby of the family who rarely speaks, but communicates by sucking on a pacifier. The family owns a dog, Santa's Little Helper, and a cat, Snowball V, renamed Snowball II. Both pets have had starring roles in several episodes. Despite the passing of yearly milestones such as holidays or birthdays, the Simpsons do not physically age and still appear just as they did at the end of the 1980s. Although the family is dysfunctional, many episodes examine their relationships and bonds with each other and they are often shown to care about one another.

The special Halloween episode has become an annual tradition. "Treehouse of Horror" first broadcast in 1990 as part of season two and established the pattern of three separate, self-contained stories in each Halloween episode. These pieces usually involve the family in some horror, science fiction, or supernatural setting and often parody or pay homage to a famous piece of work in those genres. They always take place outside the normal continuity of the show. Although the Treehouse series is meant to be seen on Halloween, in recent years, new installments have premiered after Halloween due to Fox's current contract with Major League Baseball’s World Series.
