The scene where Quark compares the federation to root beer with Garak.

Q: "I want you to try something for me. Take a sip of this. It's called root beer. What do you think?"

G: "Oh! It's vile!"

Q: "I know. It's so bubbly, and cloying, and happy."

G: "Like the Federation..."

Q: "But you know what's really frightening? If you drink enough of it, you begin to like it. Like the Federation..."

G: "Insidious!"
