Illuminatus/YMMV


 * Adaptation Displacement -- More people know of Discordianism through Illuminatus! than know of it through the Principia Discordia.
 * Funny Aneurysm Moment -- A scene where The Pentagon is targeted by a terrorist bombing.
 * Reverse Funny Aneurysm -- A chapter about a rock festival said to be bigger than Woodstock spends over a page listing off stereotypical names for fictional bands; one of the groups so named is Nirvana. In fact, not all the band names are fictional; for example H.P. Lovecraft were a real sixties garage rock group, and (the original) Nirvana were a sixties psych group.
