This one will get most carpenters:Ask them if they`re an expert on reading a tape measuring device(stanly 25') If you look at about the 19" mark there`s a diamond shaped mark on the tape very few actually know what it`s for.If they don`t know walk away shaking your head and you`re telling me how to do electrical work.If they do,better think quick.It`s got me out of a few jams with the know all tradesmen.
