Help! I can't read more than two or three pages of Dune without hearing the relevant bits of Doon rattling around in my head. I'm pretty sure I shouldn't be laughing this hard at the memory of a parody version, but... I always forget just how perfectly Ellis Weiner nailed Frank Herbert's writing style. (And I like Herbert's style.)
"BEERPAPER: Paper made from beer.
"BEERTERRYCLOTH: Terrycloth made from beer. Not as absorbent as real terrycloth, but pretty absorbent, considering."
That final "considering" gets me giggling every time.
