This wasn't clever like the other extended openings. For example, the evolution one had Moe heading the other way was clever. And the one where the Simpsons were other sitcoms (Dick van Dyke, Cheers, Brady Bunch).
I think they might have been going for a macabre funny like Edward Gorey with all the dark colors. But it really didn't make it.
If anyone ever tells you that you put too much Parmesan cheese on your pasta, stop talking to them. You don't need that kind of negativity in your life.
