To quote Matt Groening from The Simpsons Forever book: "Time has a way of slogging on". And so we come to the thirteenth year of The Simpsons' brilliant comedy.
Season Thirteen (2001-2002) marked a notable turnaround in episode quality for many fans. Mike Scully left, and was replaced as Executive Producer by Al Jean, a former EP with Mike Reiss in Seasons 3 and 4. Out were some of Homer's "jerkass" qualities, and in was a more caring Homer in favour of self-improvement (though this didn't last long).
This year marked the end of constant Homer episodes, and introduced some more character episodes - most notably, Marge-based episodes. My personal favourites here include Marge's crusade to ban sugar; Homer getting his jaw wired shut; the return of Artie Ziff; Bart's comic-strip-turned-internet-cartoon, Angry Dad, temporarily taking the world by storm; and Lisa posing as a college student (my favourite episode of the whole Jean era).
