The simpson syndrome.

Why is Homer Simpson stupid. There are several answers. He's got a pencil in his brain. Or is it the Simpson syndrome. 😕 I think they are all stupid in The Simpsons and that's the whole part with the program. But this simpson syndrome thing has really made things messed up.

As The Simpsons progressed, the episodes have conflicting facts.

You can say that it's because of the Simpson gene, since that's the earlier of the two episodes.

You can say it's because of the crayon in his brain, because that's more of a direct cause and we saw what happens when he takes it out.

You can say The Simpsons shouldve been cancelled about seven years ago.
