The more pretentious, self-servine and/or hypocritical a work is, the more it lends itself to
parody... Here's an excellent example of a research parody.

Most good parodies have a modicum of humor, although that need not be the ultimate goal. Some of the most famous parodies (especially the many parodies of writings of William Shakespeare) are biting, with little noticeable humor, but making the author's point, nonetheless...
I would add that there's a fine but deffinitive line between a good parody and satire, which serves a different purpose...
