What a world we live in, isn't it? I looked it up: "Manualism - the little-known art of playing music by squeezing air through the hands." And how great is this? Manualist.com
It would be so easy to rag on the guy and make some kind of masturbation joke, but no. If you think about it, what you're experiencing here is the cornerstone of America.

Kudos my friend and God bless this great nation!
