Variety is reporting today that FOX has given an early two-season pick up to long-running animated series The Simpsons , keeping the show--about a certain yellow-toned family who never seem to age and their doughnut-obsessed dad--on the air at least through 2008. The order takes The Simpsons into its 18th and 19th seasons, easily making it the longest-running sitcom in Fox's checkered history (it only seemed as though Herman's Head was on for that long). The order also means that The Simpsons will reach its landmark 400th episode, which will air in the show's 18th season. According to Variety, that milestone is tentatively scheduled to air on 20 May, 2007. I've had my ups and downs with the series and still manage to watch it (when they actually air a new episode) each Sunday, though the quality has been rather sub-par in recent years. Gone now are the classic episodes that you could watch over and over again (and which are shown about 18 times a day in syndication)
