Actually not so odd whilst we're tripping down memory lane. IIRC the ad agency who came up with the robots for Cadburys Smash believed in what they were doing but were totally convinced the Cadburys execs would throw it out without giving it the time of day.
The ad agency test marketed it and recorded the interviews etc and showed Cadburys the feedback and how well received it was, before they dared show them the robots.
