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.
