From “Empok Nor” (5x11)

And here we are at the climax, right as O’Brien lays his trap and Garak is at his most psycho.

Garak: They’ve come to cheer you on, Chief. Your loyal team. Apparently they’ve forgiven you for getting them all killed. [Dead Cardassians are there too.] My supporters may be fewer in number, but they’re no less loyal. I thought we agreed no weapons. 

O’Brien: What’s that in your hand? 

Garak: Well, how did this get here? But we won’t be needing these, will we. Put yours down. 

O’Brien: You first. 

Garak: Put it down, or say goodbye to the Ferengi. 

Nog: Don’t do it, Chief. 

Garak: He has nothing to worry about. I’m not going to shoot an unarmed man. What fun would that be? 

[O'Brien puts the rifle down.]

Garak: You wouldn’t happen to have another one, would you? 

[A hand phaser and a tricorder.]

Garak: Naughty, naughty. 

I know Andrew Robinson didn’t like doing this episode, but he’s SO good at it!
