I don’t know this old house, but one of the first home improvement shows in the Netherlands had a guy who looked the typical bearded handyman, think Bob Vila or Al Borland. At a certain time they added an item to the show where he would “spontaniously” ring someone’s doorbell and ask if they had some small repairs needed so he could show how it’s done, things like a leaky faucet. Easy stuff. The problem was, it was found the directors didn’t do a good job of keeping clocks out of frame. So if you looked carefully you’d see that he started at ten in the morning on a five minute job, and was done with it at three in the afternoon.

Anyway, it was later revealed that he would come in for some shots, then have the real handy people come in to do the work, and after he would take over for some finishing shots. Going on a tangent here: Eventually he was fired because he was accused of sexual harrasment. He sued the network, and they revealed there was a code of conduct specially developed for him which stated he shouldn’t bother the women on set, he shouldn’t tell jokes with sexual undertones, he had to keep working when the camera’s weren’t running and he wasn’t allowed to drink alcohol on set.
