What'd he say? Please don't make me re-watch The Q and the Gray
Here's an excerpt. The first 10 minutes of the episode are probably better than you remember, though.
Q: "I just thought that the two of you might be able to give me some advice on how to break through Kathy's icy exterior. You know, man to man."
PARIS: "My advice would be to give up before you embarrass yourself anymore than you already have. Come on, Harry. We're not going to get a straight answer out of this guy."
Q (to Neelix): "You, bar rodent, another one of these fruity concoctions."
NEELIX: "Not unless you tell me why you're bothering Captain Janeway."
Q: "Captain Janeway? Now that's a subject I want to discuss. Tell me, what are some of her favourite things. Chocolate truffles? Stuffed animals? Erotic art?"
NEELIX: "You can't bribe Captain Janeway."
Q: "Oh, no? Isn't that what you do?"
NEELIX: "What are you talking about?"
Q: "I understand that you acquire things for her, create little interesting diversions, prepare little tasty treats. After all, why else would she be so fond of your fur-lined face?"
NEELIX: "Do you want to know what Captain Janeway likes about me? I'll tell you. I am respectful, loyal and most of all, sincere. And those are qualities which someone like you could never hope to possess."
