Stop whining about how episodes dont fit together history wise or age wise. Take each episode is it's own entity. References to past episodes are just for nostalgia and humor. The only major thing that carries through on the Simpsons is death, except in the case of Hans Moleman who has a Kenny (South Park) like existance. The great thing about cartoons and the simpsons is they can get away with these kinds of shananigans
I agree that each episode should be taken on its own to a certain
extent, but episodes rely on details from previous episodes all the time. In
many cases no, it doesn't matter. Is Mr. Burns in his 80s, or is he 104?
Does it really matter, no, he's old that's all that matters. Flanders...
well he's 60, then he isn't, since he was a little kid in the 1960s. It
makes a difference in that case because it makes a difference to his
character. If Flanders is 60, and Rod or Todd are 8 or 10, how old was
Maude? certainly she didn't have Rod or Todd when she was in her 50s? So did
Flanders marry a woman 20 years younger than himself? That doesn't make
sense to his character. There are some situations where you can't just
suspend the Simpsons reality and timeline for the convenience of one
episode's storyline, unless you can tie it up in the end and explain it
away.
Many people didn't like the Armin Tamzarien episode, but to the credit
of the writers, they wrapped it up in the end ("no one shall speak of this
again under penalty of torture" and Agnes officially becomes Seymour's
(Armin?) mother. It was bizarre, but at least to some extent we can explain
it away when he's just plain old Seymour Skinner in the next episode. There
are certain constants - there must be. Homer's age has fluctuated a bit, and
that's ok, but he cannot suddenly be 50 for some reason in one episode. Bart
cannot suddenly become 18 so he can see an R rated movie because it's
convenient to the writers.
So what you're saying is that it is impossible for a man and a woman in their late fifties to have children? To me, this late-child thing fits perfectly in with Flander's character. What doesn't fit in, of course, is that Flanders was a child in the sixties and couldn't possibly be 60 now.
