Grand Nagus Zek unexpectedly arrives on the station. When he reveals the revisions he plans to make to the Rules of Acquisition, Quark fears he may have gone insane and resolves to find out what's going on.
- Anything but That!: When the Prophets decide to alter Quark like they did Zek, he says more Ferengi will come to investigate. But they'd never have to deal with another Ferengi again if they just fix Zek. The Prophets make the obvious choice.
- Breather Episode: After the back to back to back to back seriousness of the Past Tense 2-parter, Life Support, Heart Of Stone and Destiny, this episode is a comical romp focused on Quark.
- Call-Back: Prophet!Sisko noted that Zek wanted to see how the game ended. "The game" was how Sisko described the concept of linear time to the Prophets.
- Chekhov's Gun: When Quark moves in with Rom at the start of the episode, he finds his brother had been pilfering from Quark's bar. Later, Rom embezzles money from the Ferengi Benevolent Association.
- Flanderization: An in-universe version, according to the Prophets, who say the Ferengi didn't use to be so obsessed with material wealth.
- Inelegant Blubbering: Maihar'du spends the whole episode doing it. This is because Hupyrian servants are allowed to speak only to their masters and no one else, so he can't just tell them what happened.
- I Know A Guy: Or as Odo puts it...Odo: I have a friend at Starfleet Intelligence. And she has a friend who has a cousin who's married to the assistant of one of the members of the Federation Medical Council.
- I Need a Freaking Drink: After Zek buys Quark's bar a round of drinks, Maihar'du pours himself one and downs it.
- Opt Out: Quark plans to take Zek back to the Prophets and get them to fix whatever they've done. Rom warmly says he wishes he was going too, then says he's just not, and scurries off.
- Out-of-Character Alert: After trying to learn the future from The Prophets, they return Zek as an overly generous rube.
- Spell My Name with a "The": As with The Sisko, the Prophets refer to Zek as "The Zek".
- Suddenly Voiced: The first (and only) time we hear Maihar'du speak, even though he's a projection of the Prophets.
- Take That!: At one point, Quark and Rom try reading the first word of every page of the new Rules of Acquisition, and just get a bunch of incomprehensible nonsense. This is likely a jab at the "Bible Code" theories that were popular in the mid-1990s (and eventually resulted in the film The Omega Code), which involved taking certain words or letters from verses in the Bible, putting them through a "decoding" process, and coming up with predictions of the future. Critics of the theory pointed out that it was useful for "predicting" events that had already happened, but less so when it came to actually predicting the future.
- The Thing That Would Not Leave: Zek takes over Quark's quarters, and Quark takes over Rom's quarters in turn.
- We Want Our Jerk Back: Naturally; Ferengi society is based around being a jerk. Not only does Quark want the old Nagus back as a matter of personal preference, but the Nagus's proposed changes would likely get them all killed.
