And I suppose it's pointless even to bring up continuity, but both shows have previously been established as fictional within each other's universes. So it feels more like an "imaginary story" than anything else.
25 years of Simpsons and this is what bothers you about the continuity?

This is the show that openly contradicts itself in every other episode, hangs a lantern on it and asks what you're going to do about it.
