Welcome to the forum Woody. My dad always refered to painting not as a trade but a disease.
So, working on building site in your teens you must have been sent on plenty of errands - like going to ask somebody for a 'Long Stand' and not realizing until 45-minutes later that you had been standing long enough when the plasterer told you to go back to your boss. I know I did and I'm glad about it in a strange nostalgic kind of way.
The Electric Hammer trick was tried on me but, I'm proud to say it failed. For those of you wishing to have fun at the expense of a novice - simply drill a 1/4" nole in the end of a wooden shafted hammer and take an electrical cable from an old tool or appliance, with the plug still attached, and stuff the cut end of the cable up inside the handle of the hammer. Then watch the novice plug it in and try to get it to work. Please don't try this with a metal shafted hammer!
You'll never make yourself taller by standing on another mans shoulders.
