Rummage through your couch for change.
Rummage through your car for change.
Rummage through your friend's and family's couchs and cars.
Get your trusty old Marine Band Harmonica, a hat, cardboard and a Sharpie.
With the Sharpie, write "Give me a CEO's Pay Level and I will stop playing" on the cardboard.
Get on a bus, subway or some other place where it diffcult to leave, display the sign, put out the hat and start playing.
