What about the magic noise in the mechanical parts?

most people are not aware that mechanical parts are made in machine shops where they are pumped full of noise (which is why machine shops are so loud)

the noise must only be let out of the parts a tiny little bit at a time - if the noise leaks out all at once the parts will fail. once all the noise has escaped from the parts you have to send them back to the machine shop to be pumped full of noise again.

With electrical parts its almost impossible to get the magic smoke back in, but with mechanical parts a skilled machinist can often pump it almost full of noise again.

One last thing, if a mechanical part fails on you, sometimes you can get a little bit of noise back into it by yelling at it, kicking it, or pounding on it with your fist. This might put enough back into it so it will work for a few more minutes.
