Did they somehow not see the camera blatantly on the desk, feeding an image to the monitor, directly of the couch? Did they not see the butt imprint on the couch? Even if they didn't recognize the set it was based on, it was pretty blatant.
Well, it might have been judged by elderly Kentuckians who haven't seen porn since it was shot on film, if ever. So I don't find it surprising they went "Wow, super detailed couch! Give this guy a prize!"
