The Simpsons Too Cool Homer Iron-on Patch
The Simpsons uses a floating time line in which the characters do not physically age, and as such the show is generally assumed to be set in the current year. In several episodes, events have been linked to specific time periods, although this time line has sometimes been contradicted in subsequent episodes.
Homer Simpson is the bumbling husband of Marge and father of Bart, Lisa and Maggie Simpson. He was raised by his parents, Mona and Abraham Simpson; in the episode "Mother Simpson", (season seven, 1995) it is revealed that Mona went into hiding in the mid-1960s following a run-in with the law. Homer attended Springfield High School, and in his final year fell in love with Marge Bouvier. Marge later discovered she was pregnant with Bart, and the two were married in a small wedding chapel across the state line. Subsequently, Homer was hired to work at the Springfield Nuclear Power Plant. Lisa was born soon after, and the couple bought their first house.
The episode "That 90's Show" (season 19, 2007) contradicted much of the established backstory; for example, it was revealed that Homer and Marge were childless in the early 1990s although past episodes had suggested Bart and Lisa were born in the 1980s.
