That was based on the even more gross (if possible) case of Gayle Grinds of Stuart Florida, who was taken to the ER on a trailer in Aug 2004, along with the sofa she'd grown into. After about 6 years of complete immobility, her skin on her back (and presumably arse and legs too) had fused to the fabric of the sofa along with a 6 year mash of shit, piss, menses and probably the output of huge weeping infected wounds. Unable to have her brought inside the ER due to the stench, they attempted to attend to her respiratory crisis in the carpark; was always pointless though as Grinds died very shortly after arrival, of heart failure (and likely the oxygenated shock of fresh air: the EMTS and firemen were unable to tolerate the appalling atmosphere in her house and full respirators and air blowers were deployed).   The Palm Beach Post covered it quite extensively and how she'd come to be that way (and the details were seriously WTF) but links are no longer what they were. The basics are here, though: http://msgboard.snopes.com/cgi-bin/ultimatebb.cgi?ubb=get_topic;f=76;t=001270;p=1
