Wiring houses usually (at least in the US) requires an electrical inspection. And building boats...well, you could drown and your survivors could sue the magazine.

Chongo, ol' pard, I think you should add one somewhere that says, "If you can see it, you can hit it with a rifle/shotgun/handgun, depending upon the circumstances." And you and I both know that a Tommy gun is only okay, at best, at 50 yards -- it's better at 25, since it was designed for close-in work as a trench gun in the first place.
