A few years ago, Letterman or Leno would have a sequence where they'd show a porn movie, but cut out all the porn. It was pretty funny: each clip would be about 5 seconds long.

That's another issue that clouds the matter -- that sort of editing is clearly "review and commentary" (in this case, commenting on the use of a threadbare "plot" upon which to hang porn scenes), which is a form of protected fair use.
