Several years ago at a concert, a friend of mine tried to convince me
that if you cut the bottoms out of two beer cups and hang them on your
ears, the music sounds WAY better and more focused, especially the base
frequencies. Of course, this was at a Grateful Dead concert and the
last we saw of him for the day he was dancing through the crowd with
beer cups on his head. Since then, I have taken most scientific
theories put forth by my acquaintances with a dose of skepticism that is
exponentially related to the level (and quality) of their intoxication
during the period of "experimentation".
