Jeremy Braddock just (well, in October) published a scholarly yet extremely enjoyable book about The Firesign Theater, the brilliant 1970s-ERA audio improve group. Firesign often rolled technologies into their humor. In particular, the album "We're All Bozos on this Bus" has a long intricate piece that spins in and out of Lisp and ELIZA jokes (among many many others). The Firesign folks had had a demo of ELIZA, probably on a PDP-10. That would almost certainly have been Bernie Cosell's Lisp ELIZA, and we (ElizaGen.org) provided an image of the listing of that ELIZA, which appears as a figure in the book! (I'd tell you which figure and the page, but I loaned my copy of the book out. But if you are a Firesign fan, the book is, IMHO, fantastic throughout!)
