The Homeric Epoch: On the Simpsons retcon last night: In addition to all the many understandable timeline abuses necessary in a 20 year old show in which none of the characters age – Homer allegedly invents grunge and Kurt Cobain’s “cousin” clues him in. That would place the episode somewhere before the 1991 release of “Nevermind” or even before Nirvana’s first single in 1988. Yet later in the episode they make reference to Bill Clinton’s perjury charges, which places that scene around 1998. So that single episode spanned 7-10 years? What has happened to the well-known realism and fidelity to the facts that has made the Simpsons such a gritty, down to earth American family drama?
