I used to love pdfs in blissfully ignorance... until I recently looked up the format. You wouldn't believe this, but did you know that it's actually possible to embed a *video* in a pdf file? Embed another pdf inside a pdf in a hierarchical substructure? Run arbitrary JS code from a pdf? (Which, btw, is *not* the "official" JS, but Adobe's own hackneyed version thereof.) If you were insane enough, I bet you could implement an OS inside a pdf file. Or an FPS.
