I haven't watched this show in years but gave it a go last night. It's a spoiler for those in the UK.
Spoiler:
A strange thing happens to Ned Flanders one day when Bart's teacher Edna Krabappel accidentally falls into his arms (literally). The two strike a chord and start dating (for anyone who doesn't know, Ned's wife has been dead for years). The show ends with Ned realizing that Edna has dated just about every man in Springfield and has doubts whether he can continue his relationship with someone as easy as her. Homer and Marge then address the audience and say that the viewers will vote on whether "Nedna" is successful by going to
The Simpsons website. Votes will be counted until August but you can vote now if you care to.
