I've known a few violinists that think that both sides of the bridge should be in tune with each other (it's kind of hard to explain, but this has to be done via bridge placement and then the sound post location sort of follows too), so this sort of joke kind of works. I'm not sure if this is urban legend or not, but I wouldn't want to go into a luthier and request this sort of setup.. I prefer much the more scientific methods, like rapping on the back with your knuckles and what not
