Last night I tormented myself with visions of a plumbing-pipe based flat-panel TV mount. Measuring, counting, keeping a parts manifest. Most of this was in my sleep, except every so often I would convince myself that the device needed a crucial part that I did not know the name or availability of and WHAM my eyes would pop open and I would scrub the Internet fruitlessly for whatever seussian pipe joint I had imagined.

Hunh, I suppose that all can legitimately be considered a pipe dream. Although I am confident to do so constitutes etymology abuse.
