All October long, Cracked is catching up with some of the greatest writers in Simpsons history to discuss the most beloved segments from the “Treehouse of Horror” series. From the cursed monkey’s paw to Krusto the Clown, we’re digging into the making of some real fan-favorites.

Here’s one more “The Simpsons did it first” moment for the pile: A month before Toy Story hit theaters, “Treehouse of Horror VI” featured a 3D Homer in the segment “Homer3,” an utterly mind-blowing feat back in 1995 and possibly the boldest thing the show had done up until that point.

Maybe more impressively, it was a feat pulled off by a couple of newbie showrunners, Bill Oakley and Josh Weinstein. They’d written on The Simpsons for several seasons already, but “Treehouse of Horror VI” was just their third episode at the helm — an episode that went on to be a classic.
