First.. for those that don't know what a manualist is (from Wikipedia):
I thought about putting this out in the Entertainment thread since it is rather entertaining
Manualism is the little-known art of playing music by squeezing air through the hands. Because the sound produced has a distinctly flatulent tone, such music is usually presented as a form of musical comedy or parody. The musical performer is called manualist, who may perform a cappella or with instrumental accompaniment.
