For me, the best statement came from the guy who replaced fuses with nails:
"People think I'm an electrician but I'm not."

I couldn't agree more.

One practice I saw that concerns me is the placing of Bell boxes in direct contact with, even partially buried by, the earth. When this happens, it has been my observation that not only do they rapidly fill with mud and plant roots, they also completely corrode away within a few years.
