Wesley: Are you telling me to go yell at Salia?
Worf: No! Men do not roar. Women roar. Then they hurl heavy objects. (dreamily) And claw at you.
Wesley: What does the man do?
Worf: He reads love poetry. (Coming back to reality) He ducks a lot.

How to eat a chocolate sundae: First of all, you have to spoon the fudge around the rim, leaving only the ice cream in the middle. Then you gently spoon the ice cream around the sides, like you're sculpting it. Relish every bit, make every one an event, and then, with the last spoonful, close your eyes.
Riker: I had no idea it was such a ritual.
Troi: Chocolate is a serious thing.

Nog:Like what?

Nog:You couldn't ambush a Bollian, if he was blindfolded and tied to a tree! - The magnificent Ferengi

I don't think I'm cut out to be captain. First officer, maybe. I understand there aren't many qualifications. --Counselor Troi to Commander Riker Disaster

Worf: I have a sense of humor. On the Enterprise, I was considered to be quite amusing.
Jadzia Dax: That must've been one dull ship.
Worf: That is a joke. I get it. It is not funny, but I get it. Change of heart

Jadzia Dax: By the way, what does... "gung-gung-gung" mean?
Worf: Why do you ask?

Worf: He did?
Jadzia Dax: He seemed to be getting a kick out of it. What does it mean?
Worf: That is between Yoshi and me. Time Orphan
