When asked why he made the decision "to take Stewie from homicidal maniac to gay little song boy?," MacFarlane answered: "It wasn't a conscious decision. Characters evolve in certain ways and we found that doing the take-over-the-world thing every week was getting played out and was starting to feel a little dated. It was weirdly feeling a little '90s and believe me, if we were still doing that, the show would be on its last legs. I only half-jokingly go by the guideline that, if it's something that might possibly ruin the show, it's a story we should probably do."
