This is hardly new, and has probably been posted before, but Susan Ivanova's conversation with Ezri Tigan in Symphony of the Sword No. 5: Prelude in A Minor. An excerpt:
Quote: Hesitantly, her eager expression fading, Ezri asked, "Do you
not -need- an assistant counselor here, Commander?"
"No. No, Mock Ensign, we do not," Ivanova replied. "We are,
as it happens, all -quite incurably mad- here, and as such we have no
need of a counselor of any kind. Besides, what would we need a
counselor for?" she went on expansively. "We have Mr. Garibaldi.
Whenever any of us is feeling down, we can always count on
Mr. Garibaldi to do something to cheer us up. Like filling our
underwear drawer with oatmeal, or billeting visiting Klingons in our
quarters."
