Even though I said I wasn't going to do another season, there's just too many ideas that probably won't come from the actual show, so here's my celebertyless ideas:
22:01: "Who's afraid of the Big Bad Enviormentalist?"
When Lisa's activism to stop global warming is seen to be based on a pack of scientific lies and heresay, she begins to question what she's been taught to believe in and if she really might be going after the misrepresented evils in the world.
22:02: Treehouse of Horror 22:
"Farenheit 651: The temp at which Brass Melts"
--Lisa's leads a rebellion to stop society from destroying musical instruments because "music" is deemed bad for society.
"Knowing is half the Babble"
--When Marge has visions of the end of the world, she tries warn everyone of what's to come, but no one believes her, except for...Bart!?
--When Homer borrows Marge's wagon, he accidently hits a crotchety old gypsie, but when Homer tries to run instead of getting medical help, a curse is placed on the car and Homer suspects it might be trying to kill him on the way to work.
22:03: "The Nerdburglers"
When the CBG's store is robbed while he was on vacation at the hospital, but when the surveilence footage is revealed, it looks like Bart (or someone's similar shadow) is guilty and now Bart has to find out who "dunnit" or wind up behind bars.
22:04: "No Thanks, Giving"
When Homer learns of Ned Flanders yearly tradition of volunteering for the Salvation Military's "Bell Ringers" collection drive, he doesn't care, but when he learns he could do this to impress Lisa without having to do very much other than ring a bell and act silly, he agrees. At first Ned's happy, but after a few days, the friendly competition turns downright ugly.
22:05: "Two + Forty = Too Many"
When Springfield Elementary is closed down and is forced to merge with Shelbyville, the kids must now get up at 5:30 am to be ready for the bus by 6:30. To make matters worse, the class sizes, due to budget cuts, are twice the size and Bart's no longer a bad boy since there's just too many kids and Lisa's feels downright ignored when she's now in a class of 45 students. Meanwhile, Homer and Marge are trying every trick in the book to keep Springfield elementary from being torn down and turned intoa Greynhoud bus stop and Park and Ride.
22:06: "The Wives of Clause"
When Chester K. Woodland, Springfield's most beloved Santa, comes to pose for photos with the kiddies, he's accused of sexual harrassment by Helen Lovejoy (who's one of the organizers). Upset, Marge becomes an MELF (Motherly Elf) in the show and finds out white kind of Man Mr. Woodland is in his Gingerbread House.
