A bit more context-based version is the Force Your Connections trick from the Mind Performance Hacks book. It's basically how all those movie/computer game/postmodernist paper online title generators work, except the grammar that defines the generated phrases can be relevant to a problem domain. Morphological analysis is apparently the version of this that's presented in a way in which it sounds justifiable to hire a very expensive consultant to do it for you.

I think people who don't believe in the supernatural and still practice "magic" do something like this with a Tarot deck.
