Does it make any sense to use an outward facing vapor barrier on the interior side of an exterior wall?

I was thinking of using a vapor barrier installed backwards between the sheet rock and the insulation. Good Idea or bad idea?

Wally, a vapor barrier does not face one way or another. Did you mean to say a radiant barrier? Browse this list for illuminating discussions of such topics.
Wally,
Most walls don't need a vapor barrier. For more information, see Vapor Retarders and Vapor Barriers.
