This is an odd AMA (by Simpsons director)

[grue]

I forgot about arguments that I put into paper on an academic level. it's absolutely likely that he doesn't remember details of particular Simpsons episodes, when you do intensive work like that you just tend to focus on the task at hand and move on once it's done.

also the Itchy and Scratchy thing:

"There was an episode at a comic con style convention or something with an itchy and scratchy producer or artist who was fielding questions. A nerdy convention goer stands up and asks OPs question."

...you'd be surprised at how many people simply aren't up to date on memes.



that being said, he could be trolling.
