The Simpsons creators have teased an episode they say fans have been waiting for since 1989 in a teaser for the upcoming season 36. According to a synopsis for the first episode of the new series, "Bart's Birthday" the eldest Simpsons child "celebrates the most shocking birthday party of his entire life — one that might just change everyone in Springfield forever." Fans have speculated that an episode could include aged versions of the characters — something that has not been seen since the show began in 1989. Season 36 premieres on Fox on Sunday, 29 September.
