Ideas for continuing TV shows after their series finale?

By the time That 70s Show was in it's final season, the main characters all seemed to have other careers going on and didn't give a sheet about the show, themselves. Continuing the show would simply be a waste of money, time and film... not to mention just sad. Your idea would be good, if not for the fact that those involved with the show gave up on it, before it's finale. As for a follow-up to a series ending, I'm drawing a blaknk at any series that I'd want to see continue but I think there are a lot that could be done simply for shits & giggles. I'd love to see some show like take a turn for the worst. Married with Children could've shown Kelly knocked up, Al in prison for not paying alimony to the very rich and powerful Peggy, after their divorce.
