Last night's Treehouse of Horror episode of The Simpsons, the show's annual Halloween-themed program that tends to scale up absurdity to crazy levels, certainly kept with that trend this year.

This year's episode ended with Lisa saying, "I just had a worrisome thought: If there can be two incarnations of The Simpsons, why couldn't some evil marketing entity produce millions of others?!"

Lisa's fears are realized, and we are presented with versions of The Simpsons family inspired by all manner of animated shows and pop culture references.
