Bob (Robert) Edgell,
Wealthy American worth billions who started off as an electrician with nothing, was having a house built in Melbourne and i did all the A/V and automation but not the electricals. One day Bob requested something from the electrician and was told it couldn't be done for a few days as the electrician needed his sidekick who was busy elswhere. Bob wanted it done the next day, so he went down to the local hardware store and bought himself a tool belt and a bunch of new hand tools and spent the entire following day acting as the electricians sidekick. This was about 10 years ago now roughly, maybe a bit more.

A couple of random pics of his house.
