Q-Less was surprisingly dull, and proved that John De Lancie had no business visiting Deep Space Nine. There was just no chemistry there. (It was fun to watch Sisko punch Q, at least.)

There’s also an episode where Quark is caught messing with the replicators, annoying the crew members with advertising. That was one of DS9’s all-time best scenes (“I’ll come to Quark’s, and believe me, I WILL have fun.”), but the remaining 40 minutes of that episode was a real buttnutter, about a planet of humanoids destined to die by a genetically engineered virus.
