Those two words is all I have to say about Robert Shea's/Anton Wilson's "Illuminatus! Trilogy".
Oh, and Atlanta Hope's "Telemachus Sneezed" spoof of Ayn Rand's "Atlas Shrugged" was so warm-soda-squirting-from-my-nose-funny that I almost choked after reading that passage. (If you want to see it for yourself, click the book above, and search for the text "Taffy Rhinestone" to quickly skip to that passage, or if you have the book, open up to page 538, and start from the last paragraph.)
Many thanks for the tip!
All Hail Discordia!
*Upon later rumination, I would submit that the Illuminatus! Trilogy is composed one-part of Kurt Vonnegut's "Slaughterhouse Five" time-slipping, and two-parts Robert A. Heinlein's psychedelically-twisted "Stranger in a Strange Land" and individualist/anarchist "The Moon Is a Harsh Mistress". Yes, Joseph Heller's "Catch 22" predates Vonnegut, but Vonnegut's prose doesn't both annoy and amuse the reader, something I would say makes it a better fit.
