My wife pretends she isn't impressed, insisting that it would be lot more useful if the thing would work after I was finished with it.
Some women just seem to lack an appreciation for fine engineering.
So when I was told the garage door opener was not functioning, I put on my tool belt and went out to take a look. My tool belt is this thick leather job with all kinds of hooks and loops from which one can hang hammers, ice tongs, road flares, and the like. When I put it on and walk around, I clank in a very manly fashion. I also have a plumb bob, which is a metal bullet that hangs from a string and points at the ground. No doubt this Bob, whoever he was, made quite a bit of money off this invention.
