Waaay back in the pilot; They've just picked up Neelix, who is enjoying a bath and learning about the replicator...
Neelix: The replicator, can it make me clothing?
Neelix: Maybe a uniform, like yours?
Tuvok: No. It most certainly will not.
The best line about
Tuvok was in "Muse"
, where B'lanna is expalining Vulcans to the playwright. I can't quote it word for word but it was strong stuff.
