While in full Cardassian makeup, actress Tracy Scoggins (Gilora Rejal) took the opportunity to walk around the Paramount lot, "scaring schoolchildren on buses" before security called the DS9 set, saying, "Could y'all do something about keeping your aliens contained over there?"
Yamok sauce was first seen in the first season episode, Progress (1993), and was created by former series Producer Peter Allan Fields. Ira Steven Behr said of its inclusion in this episode: "Two of the things [Fields] gave us were Yamok sauce and self-sealing stem bolts. They're silly names and I like silly names, so, every now and then, we just like to bring them back."
René Echevarria oversaw most of the final stages of the story development, and even came up with #34 and #35 of the Ferengi Rules of Acquisition, with the approval of Ira Steven Behr.
The comet the visual effects team developed for the episode was a model built by Tony Meininger, and not a computer-generated image. The artistic challenge, according to Gary Hutzel, was determining what the inside of a comet looks like.
The original draft included the Rule of Acquisition, "faith can move mountains of inventory", which was created by David S. Cohen and Martin A. Winer. Though this did not make it into the final script, Ira Steven Behr liked it so much that he included it in his books The Ferengi Rules of Acquisition (p. 50) and Legends of the Ferengi (pp. 86-87), where it is #104.
