Which episode was it when...
...OFF was playing a board game and Bart tried to cheat, and OFF wound up in a brawl?
...realizing they need help, the family went for counseling?
...the family went camping?
...Marge kicks out Homer, leaving him to sleep in Bart's treehouse?
...the state meddles in the way the Simpsons interacts with each other?
Please don't bother trying to answer these questions. I know the answers, and there is more than one correct answer to these questions. I just felt like pointing out how the episode of January 6, 2001 seemed to recall a record number of previous episodes, including at least three of the earliest episodes from the first season. IMHO, it was probably deliberate.
Here is my idea for another "new" episode:
Miss Hoover goes on vacation and Lisa is inspired by a substitute teacher, prompting Homer to write another hate letter to Mister Burns, which he must try to retrieve before Bart again tries to jump Springfield Gorge on his skateboard, this time simply to taunt Lisa, who is assigned to babysit him again.
It's up to Marge to try to stop Bart from jumping, but a ride in a helicopter sparks her second nervous breakdown, prompted by her fear of flying. Marge spends some time in a sanitarium with a man who thinks he's Michael Jackson. Jackson advises Marge to seek treatment in a casino, which she does, but that ignites her gambling problem once again. Maggie responds to all of this by shooting Mister Burns again.
Then, another angel fossil appears to warn everyone about another comet heading toward Springfield. The comet disintegrates in the air and changes into a hurricane, which again destroys Flanders' house.
The wounded Mister Burns discovers who shot him, and responds by firing Homer again, who in turn spends his spare time becoming Springfield's safety advocate. In order to be taken seriously as a safety advocate, Homer buys a hair tonic to finally grow some hair. In order to pay for the hair tonic, Homer again takes a job as a department store Santa Claus.
Is that convoluted enough? :)
