"Jared Has Aides" was written and directed by series co-creator Trey Parker. The episode, which heavily satirizes former Subway spokesman and weight loss advocate Jared Fogle, was inspired by the fact that Parker and Stone had seen several Subway commercials featuring Fogle; as Parker said, "there was a Jared commercial on all the damn time, and it was getting pretty out of hand." The subplot from the episode, featuring Butters faking losing weight in order to strike a deal to film commercials with City Wok, was inspired by Parker and Stone wondering if Fogle really lost weight by eating a diet consisting entirely of submarine sandwiches, with Stone saying on the commentary that "I could go gain 20 pounds, and then eat nothing but McDonald's. I just wouldn't eat very much McDonald's." The character of Jared Fogle would later return in the fourteenth season episode "200", as one of several celebrities who returned to South Park for justice, and again, albeit briefly, in the season nineteen premiere "Stunning and Brave".
