And that reason is that he has a crayon stuck in his brain.

While the show has been on for 25+ years now and many of the personal details for all the characters have been re-written, over-written, and reconned, the fact remains that Homer is stupid because he stuck a crayon up his nose as a child where it impinged on his brain.

Making matters worse, Homer had the crayon removed, didn’t like living as a near moron, and then reinserted it.

Homer chooses to take the blue pill, or crayon as it were.
