Odo: But don’t worry – I plan to investigate the Klingons, the Bajorans, Quark, the visiting Terrelians…
Sisko: You think Quark had something to do with this?
Odo: I always investigate Quark.
Star Trek: Deep Space Nine, Season 3, Episode 17 – “Visionary”
Odo: There’ll be no live vole fights on the Promenade, Quark.
Quark: I would never be party to anything so cruel and inhumane. But, of course, if some Cardassians happened to bring their voles along and they happened to get into a fight, I could hardly be held responsible for…
Odo: Oh, yes you could.
Sisko: And you will be.
Star Trek: Deep Space Nine, Season 3: Episode 15 – “Destiny”
Star Trek: Deep Space Nine, Season 2: Episode 2 – “The Circle”
Odo: Quark, I hate to do this, but I guess I’ll have to…
Quark: That’s not fair!
Odo: I haven’t done anything yet.
Quark: Whatever you’re going to do, it’s not fair.
Star Trek: Deep Space Nine, Season 1: Episode 4 – “A Man Alone”
Odo: I’ll never understand the humanoid need to … couple.
Quark: You’ve never “coupled”?
Odo: I choose not to. Too many compromises. You want to watch the Karo-Net tournament, she wants to listen to music, so you compromise: you listen to music. You like Earth jazz, she prefers Klingon opera, so you compromise: you listen to Klingon opera. So here you were ready to have a nice night watching the Karo-net match and you wind up spending an agonizing evening listening to Klingon opera.
