this does not answer your question at all but.....
Awhile ago I had a landscaping company and worked on the show Curb Appeal on cable as the crew. It is so funny. The job on camera was made to look like we did it in 48 hours it actually took us 3 weeks. The host would sit around talking to his agent or whatever while he drank tea. Then when the camera was on he would get down and dirty as if he as been in the trenchs. He would say stuff like " Could you get someone to loosin up the soil for me so I can get a big shovel full?" Granted it was our job to do all the work and we were contracted for good money. I just thought that the people involved would at least be interested in the project and be a little more involved.
