I think part of me says DS9. I knew the kind of humor would work. I mean Quark is the miscievous one being watched by Odo all the time, that's funny enough. But I remember a moment where this bante was played out in the most obvious of ways. I don't remember the episode, but it was early on. i think "Vortex." Any Quark is doing or plotting such and such, and Odo from off camera or maybe from behind him says "QUARK" and they just show Quark's startled face as he jumps in place and drops whatever he's doing. I don't know, that moment was not only funny as hell, but was also the most literate interperpretation of their dynamic.
I loved the scene of Sisko and Dukat trading barbs in "Ties of Blood and Water," Sisko's asking why he's not a legate, and Dukat mentions the pretentiousness of being called a legate or emissary (LOL) and then Sisko adds Dominion puppet. LOL again!
