I guess I'd mention the
Cineverse Cycle. It's actually three books,
Slaves of the Volcano God,
Bride of the Slime Monster, and my personal favorite
Revenge of the Fluffy Bunnies.
The basic premise is that movies are reel, er ... that is "real" ... just not
here. There's a whole other series of universes, called the "Cineverse," in which movie physics and laws all literally apply: the good guys never run out of bullets, you can identify the bad guy by his facial hair (but never until it's too late), etc.
It ought to be horrible, but it's really quite a fun romp. They're a bit hard to find: I ran across the first volume in a used book store one time, and spent several years tracking down the other two. I basically had to wait until bookselling got up to speed on the intartubes. It's fairly easy to come up with copies now, though the prices are what you'd expect from the situation.
If you like farce, you'll probably like this stuff.
