The BBC has a show like that...BBC One's Rogue Traders. They set up and confront them.
One old lady said she needed a tv fixed. (The BBC guy just unplugged the cable from the wall.)
The contractor shows up, pours Red bull all over the wire, then sells her a new TV, New antenna, new cable run for like 700 Euros.
Thier is a bunch of them on YT.
As far as HoH....noticed they are wearing a lot more safty gear in the new shows, Mask mostly.. Wait till after 4-22-10 when the new EPA law takes effect. Any home improvement show filmed from then on will have to do RRP regs if the work is in the US and in homes built before 1978. I bet he wont do work in the states after that...
