I just have this feeling that this episode... may or may not have had some influence with the "Bart and Homer's Excellent Adventure" segment of Treehouse of Horror XXIII. I mean, there's a lot this episode has in common with that segment, particularly with the purpose of altering the past. Maybe it's just me, I don't know, but considering Chap Stewie was released just a year and a half after Treehouse of Horror XXIII, I am inclined to think this.
